There are a lot of fashion-related things we would have done differently had we had our non-teenage brains in our teenage bodies. No DIY fringed T-shirts. No blowing our babysitting money on that one locket-chain bracelet. No dressing like Alex DeLarge for that entire month. The biggest regret though, was Prom. And if we could take away those memories (and photos) or those spangled, chiffon-choked, technicolor horrors, we would. Nancy Phatsaphaphone agrees, and has dedicated a whole board to "Prom Dress Redos." Filled with red carpet sensations, runway scene-stealers, and actually shoppable gowns, this board will fill you with regret (while giving you something pretty to look at). Hey, we never said Pinterest is all rainbows and sunshine.
