Retrousse literally means upturned. Tits with a slope that upturns to the nipple, like a ski slope; preferably with nipples that face up. What counts as a Retrousse Tit? The top half of the tit should be flat at most, but concave is more perfect. The nipple should be either pointing out or up. A nipple that points up has more leeway for having a flat top. Must be a side profile pic or at least an off-center pic of the tits so the slope can be properly seen.
