Go as a squirrel to a fancy dress party and make your own furry tail that is the right length for you. Use a long-pile faux-fur fabric in a shade of brown or grey to make a realistic-looking squirrel tail, or use the same kind of fabric in a wild colour such as pink. There is a way to get your squirrel tail to stand up, bend and hold its shape, since squirrels are often seen with their tails bent up. Find the materials you need at your local craft shop.
Fold a yard of long-pile faux fur fabric in half, with the furry sides facing each other. Measure and trace with sewing chalk, a length of the fabric that is 60 cm (2-feet) long, 15 cm (6-inches) wide on one end and tapering down to 9 cm (3 1/2 inches) on the other end. A squirrel's tail is not all one width -- the end is slightly wider than the base. Insert pins within the traced lines to hold the two sides together, and cut along the lines with scissors.
Sew the edges of the two sides together, about 0.5 cm (1/4 inch) from the edges all the way around. Start at one side of the wider end, go all the way around to the other side, and leave an opening at the end. Turn the tail right side out so the furry part is facing out.
Stuff the tail with craft stuffing along the length, but don't stuff it all the way full. Straighten a wire coat hanger and trim it to the length of the tail with bolt cutters. Insert the end of the coat hanger along the middle of the length of the tail and finish stuffing around it. This gives the tail the ability to bend and hold its shape.
Fold the sides of the open end of the tail inward to 0.5 cm (1/4 inch) on either side, and sew it shut. Attach the narrower end of the tail to the back of a belt with epoxy adhesive. Wait 24 hours for the adhesive to dry before wearing your squirrel tail.
