Women’s Shapewear Weightless Comfort Shortie Slimmer. If you like Spanx skinny britches you’ll love these panties. And you’ll love the price being a fraction of the Spanx. Fit is perfect, material is soft and so lightweight yet reasonably strong providing smooth lines from waist through upper thighs. Surprisingly, legs don’t roll up. Wish there were more colors available on the shorty like the bronze offered on its sister product, a longer leg version.
