You will need; A purple tartan kids skirt, a purple wig, pink webbing, a meter of stretchy black sports fabric, scissors, needle & thread, pins, a china marker, a marking pen, a length of elastic, velcro, black vet wrap, a measuring tape and a sewing machine.
The total cost for the materials was $15. I got the skirt at a second hand shop and bought the fabric out of the remainders bin. The black fabric for the mask and cape should be stretchy sports fabric. You don’t have to do any hemming and the fabric has a little “give” to it for doggie comfort. You can buy vet wrap at any horse tack shop and some pet stores.
