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 a baseball tee.
