Hi Jane, Blair's clothes typically run small, so if you order X-large, it will fit as a large. You might find more turquoise in the larger size. ALSO, Blair's hooded sweatshirt is polyester-cotton, you could order 20 white and you could use Rit dye to die your own, tie dye with Jacquard tie-dye kit, even multi-dye--no 2 shirts would look the same. You can do it, Jane! A couple years ago I dyed 20+ white T-shirts into many versions of turquoise & white, turquoise, white and purple, then I paint on them (Jacquard textile paint). And you can do that too!
