Great coverage for a chesty gal with smaller band size
Size: 34F, Color: Gentle Rose
I don’t know why I can find bras that fit better on Amazon than in store, but this one is a good one. It fits well and is as comfy as you can expect from an underwire. It has zero lining and that can be an issue, so pay attention to that if it is important to you for the nip coverage!

Did not last long
Size: 44E, Color: Black
I really like this bra very much, it was very comfortable and fit well, but the wire popped out of the fabric in less than a couple of months. Very frustrating.

Good bra but doesn't last long
Size: 40H, Color: Brown Purple
Love these bras...BUT...after just a few short months they have broken. I bought a bunch of these at first because they are very comfy and fit well. However, I now only have 2 left because the underside has broken on all the rest. It has snapped on 2 of them and 3 other it has popped through the lining. I'll have to find something else.
