I bought this for my daughter to wear under her wedding dress. Her normal bra size is a 32D, after reading reviews on other sites people had posted it seemed as though the bra ran small. I wanted to order a 34D because of the reviews but it was out of stock. We were under a time crunch with getting the dress altered and could not find anything like this in the stores where we live. So we decided to go ahead and order the 32D. Well it arrived today and my daughter put in on, the cup size is perfect, out of the 9 hooks up the back 7 were pretty easy to hook the top two were pretty tight but she said she could live with that because everything was great. I think the 34D would have been too big. And another thing the description of “Low Plunge” is correct the top hooks in the back hit my daughter at her waist so nothing will show in her low back wedding dress. My daughter is 5’6″ and has an hourglass figure, if someone was larger in the waist you may need to go up a size and down in the cup, hope this helps someone else.
