When you are finished, you can turn your t-shirt inside out and try it on!
Tuck the sleeves of the well-fitting shirt into the armholes before you begin. Leave the sleeves of the ill-fitting shirt untucked and spread out. Make sure that both shirts are buttoned up all the way as well.
Tuck in the sleeves on your well-fitting shirt all the way to the sleeve seam. This is where the shoulder and sleeve meet on your shirt. Do not trace around the sleeves. Only trace around the sleeve openings.
Cut the sleeves completely off of the body piece of the shirt.
Do this for both sleeves.
Do not sew across the armhole openings. Leave these open so that you can reattach the sleeves.
After you finish sewing both sleeves into place, you can turn the shirt inside out and try it on!
If you are tailoring a button-down shirt, then make sure that you button it up all the way before putting the shirt on.
You may also ask a friend to do this for you if you find it difficult to pinch and pin the shirt you are wearing.
After you cut away the excess fabric, your shirt will be ready to wear. Turn it right side out and try it on!
