Size down, they fit a size larger. They're 5.95 a pop and thicker than H&M t's
i got them 3.55$ they were on sale. thick nice cotton but they shrink tho. xs fitted me well for a few wears but now they are too small. if you wear medium then size down 1 size. if you wear small, then stick with small.
good deals...very comfy tees!
