Our Gray Child Size Long Sleeved Tee Shirt in breathable 100% cotton knit makes an ideal base layer to create an easy mouse, elephant or shark costume, when paired with our fun animal ears and noses. Add some donkey ears and teeth for a cute donkey costume, or add a black bandit mask for a raccoon costume. This comfortable solid color basic is also perfect for layering under a sleeveless costume if your child trick-or-treats in colder weather. Comes in Youth Sizes S through XL to fit a range of ages and sizes.
