Attending a formal wedding as a guest comes with its own set of styling decisions, and choosing the right hairstyle can make or break your entire look. A side bun is one of the most versatile and elegant updos you can wear to a wedding celebration. It keeps your hair neatly in place for hours of dancing and socializing, while still looking polished and photogenic from every angle. Whether you have short, medium, or long hair, there is a side bun variation that will flatter your face shape and match the tone of the event. From classic and sleek to textured and romantic, the options are nearly endless. Here are 20 formal wedding guest side bun hairstyles worth trying for your next invitation.
1. Classic Low Side Bun
The classic low side bun is a refined and traditional choice that works beautifully for any formal wedding setting. It sits just below the nape of the neck and slightly off-center, creating a graceful and balanced silhouette that complements almost every face shape. This look is best achieved by gathering your hair at the nape and twisting it smoothly into a tight, secure bun pinned to one side. A light-hold hairspray and a few bobby pins are all you need to keep it in place from the ceremony to the last dance. It pairs especially well with statement earrings and off-the-shoulder or strapless dresses. This hairstyle communicates quiet confidence and understated glamour, making it a safe yet stunning pick for any wedding guest.
2. Messy Side Bun With Loose Tendrils
There is something effortlessly chic about a messy side bun that still looks put-together enough for a formal wedding. This style starts by loosely gathering your hair to one side and twisting it into a soft, undone bun. The key is leaving a few face-framing tendrils loose around your forehead and ears to soften the overall shape and add a touch of romance. You can use a texturizing spray or dry shampoo to give the hair more grip and volume before twisting. This relaxed updo works on nearly all hair lengths, though medium to long hair gives the most natural-looking result. It is the perfect choice for a garden or outdoor wedding where the vibe is a little more laid back but still dressy.
3. Braided Side Bun
A braided side bun combines the intricate detail of a braid with the elegant structure of a classic bun, making it a standout option for a wedding. Start by creating a side braid—either a traditional three-strand braid or a more detailed fishtail—along one side of your head. Then gather the rest of your hair and the braid together, twisting them into a bun positioned at the nape or slightly lower. The braid adds visual interest and texture, giving the simple bun a more elaborate and customized feel. This look works especially well on thick or long hair where the braid can really stand out. It is also a great option for second-day hair when your natural texture gives the braid extra grip and dimension.
4. Twisted Side Bun Updo
The twisted side bun updo takes a simple concept and elevates it into something refined and polished. Instead of a standard coil or braid, sections of hair are gently twisted and wrapped around each other before being pinned into a bun on one side of the head. This technique creates beautiful ridges and lines throughout the updo, giving it visual depth and an almost sculptural quality. It looks especially striking on sleek, straight hair, but also works well on hair with a slight natural wave. A small amount of styling cream helps control flyaways and keeps the twists defined. This hairstyle strikes the perfect balance between formal and modern, making it ideal for an evening wedding or a more traditional venue.
5. Elegant Side Bun With Floral Accessories
Adding floral accessories to a side bun is one of the easiest ways to personalize your wedding guest hairstyle and tie it into the event’s overall aesthetic. Whether you choose a single statement bloom or a cluster of small delicate flowers, placing them at the base or tucked into the bun creates a stunning focal point. Fresh flowers, faux botanicals, or floral hair pins all work beautifully depending on your preference and budget. This look is especially fitting for spring and summer weddings, garden ceremonies, or any celebration with a romantic or nature-inspired theme. Keep the bun itself relatively simple and smooth so the floral element really shines. This combination exudes femininity and charm without overshadowing the bride.
6. Sleek Side Bun With Deep Side Part
A sleek side bun paired with a deep side part is a sophisticated and modern option for wedding guests who prefer a clean, polished look. Start by creating a sharp side part far to one side, then smooth your hair back using a fine-tooth comb and a lightweight gel or pomade for shine. Gather the hair low on the opposite side and twist it into a neat, tightly pinned bun. The deep part adds dramatic asymmetry and draws attention to your eyes and cheekbones. This hairstyle works wonderfully on straight or slightly wavy hair and suits formal evening weddings, ballroom receptions, or any event with a contemporary dress code. It is minimal, architectural, and incredibly elegant.
7. Vintage Hollywood Side Bun
Channel old Hollywood glamour with a vintage-inspired side bun that evokes the timeless beauty of classic film stars. This look features smooth, waved hair swept to one side and pinned into a soft, voluminous bun just below the ear. Soft finger waves at the front and a gentle wave pattern through the lengths add the signature retro touch. A red lip and cat-eye liner pair perfectly with this style for a full glamour look. This side bun is ideal for formal evening weddings, black-tie events, or venues with an art deco or vintage theme. It works best on medium to long hair and can be enhanced with a sparkly hair clip or vintage-inspired pin for an extra dose of elegance.
8. Side Bun With Face-Framing Curls
A side bun with face-framing curls is one of the most flattering and universally appealing wedding guest hairstyles. The bun itself is placed low on one side, while curled sections are left out around the face to softly frame your features and add a romantic touch. These curls can be loose and bouncy or tighter ringlets depending on your preference and face shape. The contrast between the structured bun and the flowing curls creates a beautiful visual balance. This style is forgiving, easy to customize, and works on almost every hair type and length. It is especially well-suited for romantic wedding venues like estates, vineyards, or historic churches where the aesthetic calls for something soft and timeless.
9. French Twist Side Bun
The French twist is one of the most iconic updos in hairstyling history, and adapting it into a side bun version gives it a fresh, modern update. To create this look, sweep your hair to one side and twist the lengths upward, tucking the ends inside and pinning them securely to form a sleek vertical roll. The result is a clean, sculptural shape that sits diagonally at the back of the head with the bulk shifted to one side. This hairstyle is sophisticated, architectural, and instantly elevates any outfit. It holds up remarkably well throughout a long wedding day and photographs beautifully from every angle. Pair it with a pearl or crystal hairpin at the twist for a classic finishing touch that feels both refined and special.
10. Textured Side Bun With Volume At The Crown
A textured side bun with added volume at the crown gives a nod to vintage elegance while still feeling current and fresh. To achieve this look, backcomb or tease the hair at the crown for lift, then sweep the lengths to one side and form a loosely pinned bun at the nape. The volume at the top creates a beautiful, face-lifting effect, while the textured bun adds interest and dimension. This style works particularly well for fine or flat hair types that benefit from extra body and movement. A light mist of hairspray holds the volume in place without making the hair stiff. It is an excellent choice for formal indoor weddings where a more structured and glamorous look is expected.
11. Side Bun With Pearl Hair Accessories
Pearl accessories have made a major comeback in bridal and formal hairstyling, and incorporating them into a side bun adds instant elegance. Whether you use a pearl-encrusted comb, individual pearl pins scattered through the bun, or a delicate pearl headband leading into the updo, the effect is refined and luxurious. Pearls pair beautifully with almost any hair color and wedding color palette, making them a safe yet elevated accessory choice. Keep the bun smooth and slightly low so the pearls stand out as the focal point of the hairstyle. This look is ideal for classic, traditional, or black-tie weddings where the dress code calls for timeless sophistication. It is understated but never boring.
12. Bohemian Side Bun With Braided Crown
A bohemian side bun with a braided crown is the perfect choice for a wedding with a relaxed, earthy, or festival-inspired atmosphere. Start by creating a Dutch or French braid along the hairline from one temple to the other, then gather all the hair including the braid and twist it into a soft, low bun on one side. Pull a few pieces loose for a naturally undone finish. This look celebrates texture and movement, making it ideal for wavy or curly hair types. It works beautifully at outdoor weddings, barn venues, beach ceremonies, or any setting where the vibe is free-spirited and romantic. Small wildflowers or greenery tucked into the braid complete the bohemian aesthetic perfectly.
13. Side Chignon With Sweeping Bangs
A side chignon with sweeping bangs is a beautifully tailored updo that feels both polished and romantic at the same time. The chignon—a French term for a low, elegant knot—is positioned at the nape and slightly to one side. What sets this version apart is the addition of softly swept bangs that drape across the forehead, creating a gentle and feminine frame for the face. This detail softens the formality of the updo and makes it feel more approachable and wearable. It is a fantastic option for women with bangs who want an updo that still incorporates their signature fringe. This style complements both traditional gowns and modern cocktail dresses, making it one of the most versatile choices for any formal wedding.
14. Curly Side Bun For Medium Hair
Not all side buns require long flowing locks, and a curly side bun is proof that medium hair can look just as glamorous. This style works with your natural curl pattern or with curling iron-created waves. Simply gather the mid-length curls to one side, twist them gently, and pin them into a full, textured bun. The curls create natural volume and dimension, making the bun look richer and more substantial than it might on straight hair. Leave a few curls loose around the face and neck for added softness. This updo is ideal for women who want a low-maintenance yet formal look that celebrates their natural texture. It is especially fitting for summer and early fall weddings.
15. Side Bun With Jeweled Hair Comb
A jeweled hair comb is a stunning accessory that can instantly transform a simple side bun into a show-stopping formal hairstyle. Choose a comb with crystals, rhinestones, or metallic accents that complement your dress and jewelry. Insert it at the base of the bun or along the side where the hair is gathered, and it acts as both a functional piece and a sparkling ornament. The key is to let the comb be the star by keeping the bun itself clean and relatively simple. This hairstyle is perfect for evening weddings, holiday celebrations, or any formal event where you want to add a touch of glamour and sparkle. It is one of the easiest ways to make a basic updo feel special.
16. Rope Twisted Side Bun
A rope twisted side bun uses a simple but visually striking technique where two sections of hair are twisted around each other like a rope before being coiled into a bun on one side. The resulting texture is bold and dimensional, giving the updo an intricate appearance without requiring advanced braiding skills. This style works on all hair lengths from medium to long and can be adapted for both sleek and textured finishes. The rope twist adds visual interest and makes the bun look more detailed than a standard coil. It is secure enough to last through hours of celebrating and dancing, making it a practical yet beautiful option. This look pairs especially well with minimalist or modern wedding attire.
17. Side Bun With Wrapped Hair Band
A side bun accented with a wrapped hair band is a clever and stylish technique where a thin strand of hair is wrapped around the base of the bun to conceal the hair tie and create a seamless, polished finish. This small detail makes the updo look professionally done and intentionally styled rather than quickly thrown together. The bun can be placed low or at mid-height, depending on your preference. This technique works beautifully on sleek, straight hair where the wrapped section is clearly visible and adds a refined touch. It is a simple but effective way to elevate a basic side bun into something that looks red-carpet ready for a formal wedding celebration.
18. Half Up Half Down Side Bun
The half up half down side bun is a fantastic compromise for women who love the elegance of an updo but also want to show off their hair’s length and texture. The top section of hair is gathered and twisted or braided into a small bun on one side, while the rest is left flowing freely with soft waves or curls. This style gives you the best of both worlds—structure and romance, polish and movement. It is especially flattering on long hair and works well with both straight and wavy textures. This look is ideal for semi-formal to formal weddings and transitions effortlessly from the ceremony to the reception. A delicate accessory at the bun adds an extra touch of celebration.
19. Asymmetrical Side Bun
An asymmetrical side bun is all about intentional imbalance and artistic placement. Rather than centering the bun at the nape, it is positioned noticeably lower on one side, creating a dramatic and eye-catching silhouette. The asymmetry draws the eye and adds visual intrigue to the overall look. You can keep the top smooth and sleek or add volume and texture depending on the level of formality. This style works particularly well with one-shoulder or asymmetrical dresses because the hairstyle mirrors the outfit’s design. It is bold without being over the top, making it a confident choice for fashion-forward wedding guests who want to make a stylish statement while still looking appropriate and elegant.
20. Knotted Side Bun Updo
The knotted side bun updo is a creative and modern take on the traditional bun where the hair is literally tied into a knot before being pinned in place. This technique creates an organic, sculptural shape that looks intentional and artistic. Start by dividing your hair into two sections, then tie them together like a simple knot and tuck the ends underneath, securing everything with pins. The result is a unique and textural bun that stands out from more conventional styles. It works best on medium to long hair with enough length to form a proper knot. This hairstyle is perfect for weddings with a contemporary or minimalist aesthetic where guests want something fresh and different from the usual updo options.
