I haven’t been updated throughly on the 1400 pages here, but there is a pretty damn good Wampa full-body costume on sale here in Norway in my local antique, movie-geek store.
When The Empire Strikes Back Hoth Battle scenes were shot here in Norway, it created Star Wars fuzz here as well. That resulted in the making of a lot of costumes for the Wampa to sell as merchandise upon the films release, called the “Norwegian Wampa” and some simply “The Wampa”. There are a lot of them still around.
