It's a very close fit on the sides and bottom , but the top of the cup cuts into breast tissue just like most I've tried. Stupid tall roots! The gore is a bit too wide as well, which makes the wires sit on my breast tissue in the center. I do love that it has extra silicone on the sides and tops of the cup to keep everything in place. The fit is close enough that I'm keeping it, but the search continues for the perfect strapless bra.
Wonderful bra! I just wish I could fit into it. It has lots of silicone/elastic grips on the side for extra stickiness, the band is firm but not too tight, and it's overall great at staying on, even if it was the wrong size. However, my roots are too damn tall for this bra, plus tissue migration happened, so I now ought to be a 30FF.
