2 Michael Stars V neck Short Sleeve Shirts from Anthropologie Says One Size but I am a small and has worked well for me. It is stretchy and could easily work for Med or maybe larger depending on how tight you prefer. 58% cotton 42% nylon One is white and one kind of a purple or maroon color(close up pictures are more true to color) Both have a little shimmer to it.
