This bra lifts as well as separates the girls. No uni-boob at all. I cannot emphasize strongly enough that you must be professionally fitted in this at a lingerie store if you have one. I made the same mistake others have done and ordered my normal bra size, 34D. I thought a little bit of spillage was normal. Then I went to the Panache website and found a local retailer. She took one look at the Panache I was wearing and said you need 1 cup size larger. Lo and behold, the 34DD is the best fitting bra I've ever worn. Yes, they are pricey. However, I had an augmentation that bottomed out, and my plastic surgeon was adamant that I not wear anything that smashed me flat. This bra satisfied him.
