I wished they had 3x or 4x available. Ugh
I just received my Christmas sweatshirt yesterday. It's really nice and I love it, but, as I've expected it to be, it is larger than the size I really wanted. I ordered a small size but it looks more like a medium. From past experiences, I've always known that their actual sizes are bigger so I'm careful not to order a medium, which I would normally get at stores for some clothing items. Maybe you would want to go ahead and order the largest size they have (XXL) and not miss out on having one of it. It might actually be bigger and you could always return it if it didn't fit. Here's the link to the fan club's return and refund policy page:
