It's no secret that prom dresses are growing increasingly scandalous with each spring. Whether this is a tacky evolution or a natural social progression doesn't matter, because it seems that formal dresses aren't going to go back to '50s styles any time soon. But in case you are craving a trip to more modest times, we have a gallery of prom dresses through the years. Check it out after the cut!

I personally favor the '40s and '50s prom looks, though the ones from the '70s definitely have more entertainment value!

Which prom era do you like best? What do you think of prom dresses becoming more revealing?
