I saw a photo recently of a pug in an awesome sushi costume. It wasn't my photo so I don't have permission to post it, but I'll describe it so that, if anyone's interested, they can try to replicate it. Actually, it looked pretty easy. Basically, all they did was take fabric that looked like dried seaweed and made an loop that wrapped lengthwise around the dog, from chest to "pugbutt." Then, they added a piece that went over the dog's back. To the "dried seaweed," they attached small, air-filled round orange balloons. The balloons looked like they were "filling" the seaweed loop. Specifically, the costume was a salmon-roe roll.
Hope that gives someone an idea
