I haven’t had a chance to actually wear this yet, as I bought it while on sale in the fall to wear next summer but from what I could tell while trying on, it fit well and seems like the straps will stay up, which is often a problem with open back one piece suits. I wish the bust had a support shelf or underwire though and the butt isn’t nearly as cheeky as the photos show which was a let down, if that’s what you’re looking for.
