Finally, size your shirts.  If you’re unsure, try laying a shirt you like out flat.  Measure underarm to underarm and double it.  So if it measures 20″, the shirt is 40″.  If you’re personalising shirts, make sure to get the right personalisation with the right sizing.  When you’re done.  Send it in and we’ll send you a final proof for checking before we invoice you and get the shirt ready to go in production.
