Prima Donna Response: This is one of Prima Donna best sellers and we never had comments that bands run large on Satin. Of course if band is compared to band sizing of other manufacturers it might differ as there are no industry-wide sizing standards manufacturers adhere to. Satin 016-1330 is a full coverage bra and if upper breast is not very full wrinkling may occur. In this particular case going down a size in band and up a cup (30G) might help but certainly not guaranteed. A bra with seams and lower neckline might be a better fit when Satin wrinkles on top.
