This is a pattern for a Wrestler Singlet. I also sell the pattern for the Wrestler Boots and Headgear. Since I’ve sold the singlet for a while I had to list the boots and headgear separate. So, here is the link to get the boots/headgear.

You can use a coupon code of BOTH to get the Singlet and Boots/Headgear patterns for $5.50. That’s a $1.50 off the price of buying them separately.
