I'd snagged a couple $5.99 XXL men's merino wool t shirts off SAC in the middle of the night the other night, thinking that maybe they'll be euro fit and fit my older brother.
They came and they look like they're about a men's large. I'm not sure if he's getting them, 'cause I can have some delightfully soft merino wool t-shirt nightgowns with these. They hit midthigh.
