I loved the idea of this bra as it would certainly fill a need in my closet. It has a plunging neckline but a low back, as many summer dresses and tops do. However, the sizing is not accurate at all. I normally wear a 34 C and so that is what I ordered. It fit more like a very small B cup and does not provide any coverage on the side/underarm area. I think this type of bra will only work for very small chested women.
One side of the bra was folded outward so it didn’t stay in place the right way and you could see it through my dress. If that wouldn’t have been a problem the bra would have fit a lot better.
I was skeptical about this bra, but it worked really well for my daughter's prom dress, which had a plunging neckline. True to size and very good quality for the price. The best part was that I ordered it online and picked it up later that day, so it could not have been easier.
I agree with the previous reviewers - make sure to order a cup size larger. I would not suggest wearing this as a strapless bra - when the straps are removed, the bra hangs forward a bit, and doesn’t stay against the body. However, with the straps, it’s very effective.
