The bottoms run small and the top runs HUGE!  For me.  Sigh.  160 lbs with 38B top.  I ordered the 18, which fits fine for the bottoms (I wear a size 14 Bandalino Jean for example), but the top is obscenely large.  Tried to contact the seller for possible exchange for the top.  No response.  Returning as the bottom is also unlined.

PLEASE sell separates!!!!!
