I ordered 3 XL shirts and all 3 looked and felt like XXL's. I washed and dried them on HOT and they are all now the appropriate size. Only worn them a handful of times but no complains other than the original size.
I purchased multiple sizes and colors for my business uniforms. Sizes are a little large. The light gray shirts have a different feel than the black shirts. Gray feels thinner and lighter weight than the black. These needs a topsheet for Embroidery, so make sure your decorator knows this if you are having this done.
