I'm a size 8/10 and have a 34I bust, so cute supportive swimsuits are hard to find at a low price point. I bought this on recommendation from a similarly-sized influencer, and am pleasantly surprised. I wouldn't say it's super tight on the bust, like I wouldn't play volleyball in this. But even with the thin straps, it's enough that I feel confident playing at the beach with my toddler. I would maybe size up if you want more of the rouching to show; I got a size 10 and while it fits fine, I feel like the rouching is all stretched out. Overall, it's great for the price.
