I ordered an XL and was sent an XXL. Even so, the XXL ended up being far too small for 36DD/38D breasts. The band that it meant to go under your breasts was across the middle of mine instead. Would not have been an issue if the bit that goes behind your neck were longer, but sadly it is not adjustable. Possibly might fit if you wear a pushup minimizer bra but the whole point of this lingerie design is to wear braless.
