This design is called catmouflage, I think it speaks for itself. CATS!
This design is printed in black on an american apparel tri-blend tank top in tri-gray, which is a lovely heather that has that perfect vintage shirt feel. Tri-blend fabric is made up of 50% Polyester / 25% Cotton / 25% Rayon, so it's super soft right away.
The sizing is unisex, so they're nice and long. If you're a lady, I'd suggest ordering a size smaller that what you normally wear in ladies.
Please see the last photo for sizing info.
