Most clothing is offered in sizes XS-2XL, we are working to provide more sizes and even work on a Big & Tall area to service every customer’s needs. When you purchase an item please check the description area for the type of T-shirt you are purchasing. All Bella+Canvas products run about a size smaller, so you should purchase one size larger. Most product descriptions will tell you if the item runs small, but do not rely on this. At the moment most our women’s products run a size small, but most men’s products don’t have this issue. Just please be aware when making your purchase.
