Shirt Boss uses Gildan for all of our shirts and sweatshirts. The size charts are estimates, not all shirts will be exact to these dimensions. The numbers listed are in inches, please allow up to 1.5 inch difference either way in the width, length and/or sleeves. We print to order and are a very small business who cannot afford to keep returned shirts on our limited shelving. With that said, returns within these margins of error will incur a 30% restocking/reshipping fee. Thanks for understanding.

We recommend ordering a size larger for children. We've added age groups in our chart for a guide only. Every child is different, so if you are unsure check your childs closet, measure and choose the appropriate size.
