Quoted from Bandit78:t's bargain basement Walmart quality. Glad I ordered 2 sizes larger than I wear. General rule is if there are no size details showing sizes in inches for each men's size, go 2 or 3 sizes larger.
Sounds about right to me.
I ordered a Snoopy mirror universe Star trek print about a year ago. I ordered 5X or 6X ... whatever the largest they had. It wasn't inexpensive. It arrived more like a 2X or 3X. Ofcourse they were oblivious that there was a sizing issue and wanted me to photograph a tape measure to show them. I just chalked it up to "garbage in, garbage out". Quality sized these are not. They minimize the amount fabric used to minimize cost and maximize profits.
While I like the idea of these shirts for "Hawaiian shirt Friday" at work... I'm not going to risk it.
