It's funny how people assume that you're necessarily self-conscious when you're fat. Recently a lover made that assumption -- granted, he was just trying to reassure me that I didn't need to be self-conscious with him, etc. but I never expressed such self-consciousness in the first place.
Personally, I know what I look like, and I don't look slimmer when I wear clothes... LOL
Actually, I might be accused on the contrary of having too much of an ego. ;)
Guess it's telling though how many girls out there feel self-conscious, whether they're fat or not...
