Yeah, thats how J. Crew and similar clothing stores like to design their clothes down here in the U.S. Hopefully you didn't go to Gap, Old Navy, or Ann Taylor Loft...they are even worse with the vanity sizing. I am a size 4, but I can wear a 6 sometimes, especially in pants. I am a straight up 00 at Loft. It makes me wonder how smaller girls even shop at stores like this. Oh wait...the youth section, just like OP lol.
