I measure well within their sizing guidelines for a 2XL. I bought a 3XL, and it was vastly too small. They made me send several humiliating pictures measuring both myself and the shirt, based on their sizing guidelines, when I requested a refund, and after weeks of emails, they are just reporting the issue to their manufacturer and are still refusing a refund, so far. It’s been literally the worst experience I’ve ever had ordering clothes online or shopping for clothes in general.
