I wear a 34DD or 36D in Victorias Secret, i'm 5'2 and 135lb--I sized down to a large (chart said i'd be an XL), but they stretch super nicely and fit perfect! ! I'd call this a low to medium impact bra--I think by sizing down it provides a little more support by keeping everything tighter, but the material is stretchy and not too tight and uncomfortable. Strappy accent in the back is very flattering. Very happy with my purchase!
