Not everyone is the same size or shape, and there is a difference in the measurements required for men shirts than women shirts. Ladies fit, a woman's cut are what differentiates Port Authority women's Tee-shirts from other tee-shirts. Personalize your T shirt uniform with a customized screen-printed business logo. To buy the correct size, we recommend that you find the time to order one of each size, and allow your employees to try them on for custom fit before buying uniforms for everyone. If time is not on your side, we have online charts to help you get the right fit.
