I read the reviews so I knew to order a size up. I'm a 38DD so ordered a 40DD. I probably should've gone up 2 sizes as I can only just get the last hooks on and they are straining against their stitching after one wear.
There is no push up, unless you count breast overspill. If anything, they flatten my breasts- even with the overspill. The cups are very rigid. When laying down, it's quite a look,- the mound of the cup and the small mound of my boob falling out the top.
