Sonic the Hedgehog
This was a speed build, done only in a couple of hours using leftover fabric.
The whole thing is one piece: a leotard with skirt. It's made of 4-way jumbo spandex. The skirt is pleated and edged with horse hair braid.
Ears and tail are fleece. The ears clip into the wig while the tail is sewn onto the back belt loop.
Shoes were painted with leather paint.
Ring is styrofoam painted.
Accessories were bought.
