SKIN TIGHT.  This dress is sexy, but elegant, tight, but still breathable. The pink is slightly see through, so need a fitted slip underneath.  I'm 5'8", 135;bs, 34B, and ordered a size 6.  The dress itself fit like a glove, but I do have wider shoulders, so the arms are a little snug for me.  I want to try one size up, but am afraid I will lose the great fit on the rest of the dress.  Very happy with how the dress fit, and looked.
