You ain't neva lied...
And "thinner" girls aren't exempt, either. Ladies just need to be conscious of how they look, and a full-length mirror should be a girl's best friend!
If you have a little extra chunk in the middle or on the sides (love handles -- and yes, skinny girls get love handles, too), DO NOT WEAR LOW-RISE JEANS! They are made for those ladies with near-perfect abs. If you MUST wear them, at least wear a long sweater (which is pretty played out... lol) or a blouse worn on the outside and blazer.
