They're both navy-loving purveyors of mass market preppiness: formerly loved by many, still loved by everyone under 16; consider them J.Crew's younger sisters.
In corner 1 we have Abercrombie & Fitch, the Ohio-based chain that churns out as nipple-baring ads as it does logo hoodies. Despite the obnoxious floods of cologne that cascade out of the store, lots of people wander in, having heard rumors of the durability of their jeans.
And in corner 2 is American Eagle Outfitters, the slightly more diverse manfacturer of high-school prepwear. AE is a tad less edgy than AF, giving them increased popularity with the mainstream.
Who will win this mall store sibling rivalry? IT'S UP TO YOU!
