I know this was asked a few pages back but didn't see an answer. Looking at some of the basics tees, any idea how much difference between a small in the "slim fit" and an XS in the regular fit? Going to try some on soon, but you can never get XS in stores. +1 for The Royal Tenenbaums, love the movie and the clothes. Zissou's av is money. Margot getting off the bus with Nico in the background gets me every time.
