My orca pajamas! Made them with a ton of help from a great friend. They're fleece adult-sized footie PJs I bought online then modified with a stuffed tummy and flukes. Kind of wanted a kigurumi style, but they didn't have extra-wide in my size for that sort of billowy look. The belly makes me LOOK like I need extra-wide, though! Keeping the option open for a stuffed hood sometime in the future. For convenience, the fins are stuck on with velcro, which is unfortunately only strong enough to hold on if I'm standing still.

Side view to show the dorsal and the white part that goes around the side of my legs. It turned out to be really well laid-out, which was surprising how tough it was to design out.
