This bra runs small in the cups. It also makes me feel like I'm wearing a suit of armor, which is pretty cool. First of all, it's definitely not going to slip, and it's definitely not going to slip without me noticing! The band is nice a snug and doesn't seem to move around at all.
I really wanted to like this bra since so many other reviewers do, but it was odd on my petite frame (took up almost as much of me as a crop top!) it didn't give me a great shape--not sure if the cups are too big (need 30F) or too small (need 30G)? the plastic in place of underwire was interesting, but I'm not sure if this would stay up on me...but maybe I'm just not used to strapless bras
For the fit, the band size is good and firm. I can fasten it on the loosest hook, and I usually wear 28 bands. The cups were just too small, though. I'm popping out on the top and the overspill is also making the bra itself slip down my frame. I can fit two fingers in between the center gore and my ribcage. Not good...Unfortunately, this was a no go for me...
Still, I've already ordered this again in a 30G because I can tell that this is a good bra if you get the right size. I tried it on underneath one of my favorite dresses and the shape was amazing!! It gave a crazy amount of cleavage for a strapless. The hand structure holding you up is weird, but it definitely does the job. Since this last growth spurt, I can't wait to finally get another strapless bra that fits. From what I can tell, I really like this bra
