I wear a 38 J in this bra. I went to a local store and got fitted and had been buying these bras from that store. But I decided to try on here and guess what they are half the price. I love the fit and it actually separates the girls and been told it makes me look smaller which is always a great thing. There is also a bra from another national store which is super sexy, yes you read that right, super sexy J cup bra, and fits well too but it has lace trim that will start to dig in after a few hours. I actually wear this bra more often. I now own at least two in every color. The underwire never pokes and like other reviewers have stated I sometimes forget I am wearing it, which at my size is saying something major. You won't regret trying this bra. It says hand wash but I wash them in a lingerie bag in washing machine, then hang to dry. Some are still going strong with no show of wear after three years.
