I read a lot of reviews, some not so good. I normally wear a 38D so I purchased a 38D however, it was a little too tight for my liking and came up a little farm around the sides to make me uncomfortable. So I thought I would try a 40 D  and It fits perfectly. I don't know why everyone has had the problems with the rolling at the bottom, maybe if you have a little fat roll at the top of your abdomen than that possibly is the reason for the rolling on the bar.

I have  not had that problem. It is so comfortable I don't feel like I even have a bra on. I think my biggest concern now is the washing of the bra and how it will hold up. I cannot hand wash my bras so I will put them in the delicates bag and wash them alone on the delicate cycle and then hang them. Hopefully they will turn out  in good shape. I am going to buy three more of them and get rid of all my underwire  bras. I hate them they are so uncomfortable. I have two new ones that I will keep that a whole pile I can get rid of. So glad I found this bra. Comfortable enough to sleep in Im sure however I probably wont. I recommend these bras highly However I do recommend you get one size bigger than you actually are used to purchasing.
