Ugly Christmas Sweater, Abominable Snowman Hooded Sweater
Complete with teeth (on the hood)!
Size is M. Not sure if this is men's or women's. I'd say it could be either.
Measures 18 1/2" from armpit-armpit
29" long from top of shoulder to bottom of sweater
In very good pre-owned condition. Looks like it may have never been worn.
