A fatty with trashy taste in clothing is about the worst thing imaginable. Unfortunately I see it all too often. However a slender built or "good" built girl should definitely if she's got the looks for it wear tight clothes. They look better when they fit properly. Ok so having it so tight it corsets her and forces the flesh out in rolls underneath or above constantly is bad but having clothes that fit like a second skin is so sexy. I find it extremely hard not to just go on a trashy girl smurf fest sometimes.
