Although Knuckles is my favorite character, Rouge is much more fun to cosplay! What I love most about her design in A2B is that her wings are really well defined and after going through making angel wings, bat wings look like a piece of cake!
Bodysuit: Thick black spandex
Boots: Heels covered in spandex. The hearts are made of foam and are heat formed before being covered in spandex. ($20) The boots are separate from the black bodysuit.
Boob Heart: This was a fun piece. My goal was to make the heart have an organic shape and avoid using seams and edges, but still provide support. I started with a piece of foam that I heat formed to be chest-shaped, then layered fabric and glue on both sides until it was sturdy. The front was covered in spandex and them trimmed in more spandex. It's a separate piece from the bodysuit and provides fantastic support, which is always a cosplay plus!
Gloves: Same spandex I used in the boots. A little snug because I've never done gloves before, but wearable nonetheless!
Ears: Satin, fleece, and spandex attached to a spandex covered headband.
Wings: Oh yesss. Those will come last, and probably be made of fencing wire, foam, and fiberglass.
Fabric: $30
