Whatever you do don’t look like this!

Tight clothes are sexy but make sure no one can see the outline/indentation of your underwear through them. Your body type also determines how much you can get away with. If you’re skinny like Mischa Barton you can wear as many tight items as you want. If you have curves like Scarlet Johansson just wear one item that is tight at a time. Unless however you’re going out and want to look sexy but don’t then combine tight with skimpy. If you’re bigger than Scarlet Johansson you should wear more tailored items instead of tight clothes. These show off you curves not your fat rolls. To summarize:

Skinny = You can wear tight clothing no probs
Curvy daytime = Max one tight item of clothing
Curvy evening = Tight but not skimpy
Curvy + = Tailored clothing
