For the tail, fold the black fabric in half widthwise with right sides together. Draw an 18-inch-long petal shape and cut out. With right sides facing and using a 1/4-inch seam allowance, sew the pieces together, leaving the top edge open. Turn the tail right side out and stuff with fiberfill. Hand-sew the tail just above the ribbing to the back of the sweatshirt.
Draw two triangular ears on a double-layer of black fabric; cut out. Sew the ears together in pairs, leaving the bottom edge open. Turn right side out; stuff with fiberfill. Hand-sew the ears to the top of the hood.
For the stripe, fold one white boa in half and hot-glue it to the hood and the back of the sweatshirt. Hot-glue a black boa around the attached white boa.
Cut the ribbon in half and hot-glue one end of each ribbon just below the hood on the sweatshirt fronts. Cut the second white boa in half, and then fold each piece in half. Hot-glue one folded half to each side on the front of the sweatshirt, covering the attached ribbon ends and keeping the feathers free of the zipper.
Add trim to the bottom of the pants legs, the ears, and the underside of the tail with the second black boa. Hot-glue pink fun fur to the ears. Attach a pink silk flower to each pants leg.
