Really struggling with Shefit and trying to make them work. I went down to a 1Luxe from a 2Luxe. The band is more secure, but rolls. It did on the 2Luxe as well.
The cups are really stiff in this lounge bra, and they sit on me like boob hats. I may try to remove them and update this if that works.
At this point though, I'm inclined to send this back. It fits weird.
For reference, I am a 32FF/G (UK). Definitely keeps them in place. It's nice that the straps and band are velcro, so they can adjust however tight you want. It zips in the front. But that's pretty much all that's good about it.
Honestly, it's... not really a bra. More of a compression vest. This can only give you a uniboob, it squeezes your breasts together with absolutely no separation, which gets quite sweaty and uncomfortable. Very boxy. It looks like you have some kind of a contraption on your chest. You can see it under any clothing, it's very obvious because of the zipper sticking out instead of conforming to your curves. Just not very flattering.
