Old Navy Women's Size Guide

Fit Summary

Old Navy is a US mass-market casual brand using US sizing as base standard for women’s tops. Women’s styles include everyday cotton tees, ribbed fitted tanks, woven button-down shirts, sweaters and lightweight blouses, offered in Fitted, Regular and Relaxed silhouettes. Regular-fit pieces generally run true to US size; Fitted rib and smocked styles have a snugger cut, while relaxed tees and linen-blend woven blouses feature generous comfortable volume. Cotton jersey items may experience minor shrinkage after washing; non-stretch woven shirts maintain minimal give. Fit varies noticeably between body-conscious fitted rib tops and roomy casual everyday tees. Shoppers selecting non-stretch woven button-up styles are recommended to size up for extra comfort.
