Morning... check out Tyra Banks wearing her jeans well. Sexy. A lot of women are out there and not wearing their jeans right.
Ladies, it is highly appropriate to show off your curves, whether you have them or not. If you have a flat booty/tush, jeans that have a mechanism in which you can pull on your jeans and it raises your booty/tush and gives you an enhanced curve... THAT IS THE ONE YOU NEED.
I don't know too much about women's jeans, but one thing I can say for sure: Women of all shapes and sizes, follow Tyra Bank's template for correctly fitting jeans, because saggy and ill-tting jeans are not cool for a MAN to look at.
