I love this swim shirt and would highly recommend it, just wish there was a bit more size information listed. I ordered one in a medium FSR46 and one in a medium FSR24. The FSR46 (the one with a flower pattern across the front) was about 3 inches narrower than the other one. So I had to return it and order that stye in an XL, which fits better in the body but is a bit long in the sleeves. So a medium in one style in comparable to an XL in another style. I see they all have different fits (loose or fitted, etc), but there is not information on the FSR46 on this page.

It seems very well made and cute colors and styles, I am very happy with the purchases, just be prepared to reorder in another size if necessary.
