This t-shirt is made from 100% fine jersey cotton (American Apparel brand). The design is printed with non-toxic inks (no plastics or plastisols). We recommend that you turn your garment inside-out and machine wash in cold water - hang dry or tumble dry on low (may shrink a little).

NOTE: American Apparel t-shirts fit a big snugger than most brands, especially the women's sizes!! Please review the following size chart. Thank you!
