best swimsuit ever worth the price.

### ⭐⭐⭐⭐ So far so good
*by B***E on March 27, 2026*

I bought it for my 12yo daughter who is in a swim team. It’s fine however the arms are cut a bit too wide for her so her boobs pop out if not careful. She says it hugs her in the water so it’s not a great concern anymore but it seems this is the issue with some of the tech suits. Before this, I purchased the Speedo power skin and that was worse in terms of how wide the arm holes are
