Hardly used Denver Hayes Aztec print plush pj bottom in size M

Got this for Christmas and I’m usually a size medium but it is way too tight for me. Even the cuff at the bottom I found too tight, then it got a hole as shown in picture. It is absolutely nice and warm but I wish it were a size bigger. The fabric is just nice and soft too. Has pocket on each side. There isn’t much stretch to the waist otherwise I would have kept it. Maybe stretched a half inch and that’s as far as it will go. Has been washed as well.
