A few quick things:
J. Crew's Factory store has puffer vests right now!!! Even though it's hot hot hot, it's a great price! I have a navy puffer vest and I wear it all the time during the winter. Vests are perfect layered over dresses, shirts, or even favorite sweatshirts.
Also.... Are you (or a friend) interning in NYC this summer???
I'm going to be there so let me know if you're planning on going too!
