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.

They're really very comfy, especially with the stuffed belly, and almost too warm to sleep in! Made them over the winter so it wasn't so bad then.
