The measurements are available in the photo above. This is for an American Apparel Unisex Tee Upgrade, the fit is different from the other unisex option available.
Add one of these listings per shirt that you would like upgraded. IE: If you order two shirts and want both to be Unisex, add two listings. If you only want one Unisex shirt and one Women's, please leave a note in your order specifying which shirt needs to be upgraded.
If you're not a fan of the classic fit t-shirts, you can add this upgrade to your order to change any order from a Gildan women's tee to an American Apparel cotton unisex tee.
