Greatest fashion faux pas

I agree about the tight clothes ladies.
I am a normal weight person, and by that I mean my Body Mass Index is in the normal range. Technically I should be wearing Medium size clothing. BUT, I hate tight clothes so I always end up getting L or XL shirts so the darned things don't stick to my body all over. I do not feel comfortable wearing tight clothing because, honestly, I feel naked. Argh, I wish the fashion industry would cater to the needs of regular people more.
