Get either a dark pink or red set of sweats. Then get some pink or light red material, cheap is best!
Cut this material into wide strips and sew or use fabric glue to attach to the sweat suit. Then take a pink or light red knee high and stuff it with stuffing for pillows. If you want it to stand up, bend etc, just insert a metal hanger into it before you stuff.
Sew this onto the back of the sweat pants. Wear white gloves and white shoes and you are set! I also painted my face and glued on some whiskers onto my face and used spray hair color to color my hair but you could use a hoodie and add the ears to that.
Thanks to an Michelle for this great idea.
