After looking at the measurement chart and reading reviews I decided to order true to my size which is Large. I think it fits form fitting perfectly. If you want a baggy look order a size up. I seen some people complaining about it falling apart after washing it I’d say those people didn’t read the washing instructions because if you do I don’t think you’ll have any issues. It is like a long sleeve T-shirt and fits how it’s pictured. I would definitely buy again!
