Braces can seem a bit odd to us ladies, what do you do with your boobs? These ones are cut well front and back and the main benefit is one of warmth, with no gaps around your middle they offer much more warmth than a conventional tight and top combination. They are also supportive holding everything nicely together and make your legs look extra long. We would suggest however that unlike the models in the catalogues we see that you wear a top of some description with them!! A medium equates to a size12.
