I went to target to buy a size 2 pair of pants--that I already have and fit into in a size 4--because they are on sale, and I wanted a spare in a smaller size in case I go down a size again (if I don't in 3 months I can just return them). I saw the matching skirt and shorts, and on a whim tried on the size 2. The pants and shorts technically fit (I can button them) but they are not yet comfortable; however, the skirt fits beautifully! Hell yeah!
I know, I am one of those people that wears size 2s, but I'm really not that skinny (and have a belly I am still trying to get rid of). I am convinced that size numbers (not the clothes) have gotten smaller because I do not ever remember wearing a size 2, and I could have sworn I was a lot skinnier in High School. My clothe sizes still vary greatly, depending on the item of clothing and where I buy it, but I'll take 2-8 any day over 10-14 (I think 8 is actually too big now, but doesn't look ridiculous on me).
