This is an optional add on that you put on any and all crews from any category on the site. This can not be done to hoodies because of the pockets being in the way.
Hemming is done by bringing the original "Scrunched" button of the crew up and sewing is down. All sewing is done with a sewing machine.
DO NOT PURCHASE ALONE you will be refunded, must be bought along side something to crop like a crew.
