I’m 5’6”, 130lbs athletic build. Ordered XS and it fits still a little looser than I expected. Washed to see if they would shrink not so much. The dry material is nice though, is breathable and cooling on the Pickleball courts and sandbag/KB training in hot Florida sun. I will keep but if I were you I’d order a couple sizes smaller than your average t shirt if u want it somewhat close to your body.
