Ordered a large, company sent me a medium in error. When I contacted them they said they could not exchange it because they had no more stock. Reordering from Amazon would have cost a lot more because this was lower priced from vendor. My husband tried it on anyway and surprisingly enough the medium fit. It was more fitted than he probably would have chosen if he had a choice but he said it was not uncomfortable at all.I was pleasantly surprised at the quality of the fine knit and the softness of the yarn. The tacky patterns go all the way around to the back too. Because it is acrylic, it will not and did not shrink at all upon washing, but I laid flat to dry just to avoid other items in the dryer snagging or catching on it. Hubby has gotten a lot of use out of this one already - worn to 2 Christmas parties, a Coyotes game, and a visit to see Santa. Totally a worthwhile purchase. Though we bought Coyotes sweater because we live in AZ, it is one of my favorites of the NHL tacky sweater designs. The colors are great, it is not holiday specific. The fine knit and style of the sweater are nice enough it could be paired with slacks for a business or business casual environment too (depending on your dress code?!). He get compliments on it every time he wears it and I think it looks very handsome, even if it is full of random "tacky" patterns!
