Guess vertical Striped Tshirt Shirt T Long Men's Or Women's Y2K Large Dress

This is a very long shirt! It honestly could work as a tshirt dress for a woman too. Or just longer torso. It had a thicker consistency too. Almost like sweater but not quiet. Really soft! Fabric is unknown because tag is cut, but if I had to guess a cotton blend. 20 inches pit to pit across 31 inches long.
