Alexander Wang X H&M Tshirt

Athletic tshirt from the Alexander Wang X H&M collection. NO SIZE*** I am almost certain it’s a size small but there is no tags on this shirt anymore as I cut them off when I originally bought it. I am generally a size small and this shirt is baggy on me - see last image. There is a bit of pilling throughout as well. Not sure what the material is put it is very stretchy, not see through, does not show water/sweat either.
