I have bought..
-A jacket in a size medium, and I am usually an XS... or smaller. Surprisingly it fits well in the shoulders and sleeves, but billows out like crazy. The only thing I regret was not buying the small online, for less.
-A silly shirt with pink guns on it. I thought it was cool at the time.
-A scarf with guns all over it. I thought it was cool, and I'd figure the only way I could get away with wearing a scarf was if it was dripping in manliness. Unfortunately, it's not comfortable at all.
-Socks. Very thin, some already have holes in them. I regret these.
However every time I go into the store or look online I get the urge to spend again =(
