Nice support but...
Size: 42DDD, Color: Black
I ordered this for my cousin who finds it very difficult to find bras in her size. She told me she wished she could find a good support bra without the wire because she had deep red marks under her old bra so I did some research and found this bra. She came over and tried it on and my first impression was WOW the support is great but it was very difficult for her to fasten all the hooks in the front due to her long nails. After some time she managed to fasten all the hooks and I noticed I needed to adjust the straps for her and she said it felt a lot better. This wireless bra looks so different on a woman with large breasts than the models in the picture, my cousin's cleavage was very substantial, unlike the model in the pic so if you are heavy set with large breasts, just know you will still have ample cleavage showing. After she put her top back on I noticed just how smooth her back looked, there were no bulges showing and she told me she felt like her posture was better due to the support of this bra. I have four stars due to the hooks being difficult to fasten.

You get what you pay for
Size: 54C, Color: Black
It's really nice n a great bra until u realize that the straps also have hooks, n the hooks keep coming undone n your boobs hanging out. Beware ladies you have to be big n also tall to wear this if not prepare n don't keep your important things in your bra bc if you're like me, u wanna keep the important things close to u. You will lose everything and not even realize it
