That is an informal question I recently asked on Facebook, given the fact I heard of this happening.
A whopping 99.9% said No. That is out of more than 150 that responded to that question.
Also be warned if you use a late fursuiter’s design. The family of that fursuiter can sue you. This had happened in the case of Lemonade Coyote, when several copied the same design. The family not only sued, but not only getting a perminant restraining order. But an actual cash judgment besides, which had cost the copier $1000s.
Use your own design.
