I bought these as a swimsuit. They’ll work fine for that but they’re basically gym shorts. They aren’t as short as they appear in the item photo. They also run slightly large. I have a 35” waist (size 34 jeans) and bought the Tag L (US M). There’s a lot of extra room in the waist. That size would fit a man who wears size 38 jeans. One thing I like about these is they have both an elastic band and a tie. And the tie is sewn inside the shorts so it doesn’t need to show. Also, even when fully wet, they are modest enough for a swimsuit due to the double layer despite not having a swim liner. No support though of course. They appear darker in my photo as they are wet.
