21. Gap

Gap took a look back that was actually a step forward for the beleaguered retailer. Its new collection focused more on creating well-fitting basics like khakis, oxfords, and knits, and enlisted faces like Lil Buck to help get the new message across. A collaboration with buzzed-about menswear designers helped drive more men to the stores, and it seems to have paid off, literally. This month, it seems the retailer is experiencing a resurgence in the fast-fashion industry.
