This is the first wire free bra I’ve ever been able to wear & I’m amazed. When I first put it on, it was comfortable & fit well. After a few hours of wear - while I did some cleaning and lounging - the band folded under a bit - but it was an easy adjustment & it didn’t roll like some wire free sports bras do on me. Back was smooth. Straps didn’t move. Overall, I’d give support a solid 7 (maybe 8) and comfort around the same. In the bra’s comfort defense, it’s super humid today & I was getting sweaty & felt as if every layer on my skin was irritating. For reference, I normally wear a 44d & got this in a 3x LTKcurves LTKunder100
