This quadsuit is absolutely gorgeous!!!! 8D I've been doing some planning on making my own Houndoom quadsuit, and I'm extremely picky with fabric and how it looks and lasts. I was wondering why types of fabric you used for this cosplay.
Houndoom actually has a few types of fur on him. The neck and shoulders is Black Shaggy Faux fur, The "bones" on the spine and back is a short pile teddy plush, the red is actually a medium pile orange fur with black flecks in it (It has be shaved down to give it that underneath colour), and the rest of the body is unfortunately a random one-off I bought from Spotlight~ So I couldn't tell you what that it is sorry. =/
You could always buy one type of long-ish black fur and shave it down smoother where need be, It'd probably look more natural that way.
