My daughter has been on the Y swim team for four years, and we have gone through quite a few suits. Nike suits seem to hold up better than Speedo, Tyr, or any other brand we have tried. Last year, she was swimming 5 to 6 days a week, and it never got loose. We had to retire it in March of this year because she grew, not because the suit was worn out.

Good luck, and if you find one you like, buy two or three!!!
