If your child really wants to look like a knockout this Halloween, here's the perfect getup. With a foil champ's belt and sock boxing gloves, all your pugilist needs to complete his look is a gym bag for collecting trick-or-treat candy.
Start with the gloves: Form the socks into the shape of boxing gloves, using the heel of the sock for the thumb and the toe of the socks for the fingers. Stuff with fiberfill, then tuck the ends of the socks inside the gloves to cover the stuffing and form cuffs.
Sew or pin the thumb and fingers together. Attach the gloves together with enough black yarn to drape around your child's shoulders (either by sewing or with stripes of black tape).
Next, create the belt. From the poster board, cut a rectangle with rounded ends that fits most of the way around your child's waist (the ones here are 5 by 17 inches).
Cut a vertical slit on each end of the poster board and slide his belt through (he'll wear the buckle in back).
Cut a 6-inch circle out of corrugated cardboard, wrap with foil, and secure on the back with duct tape.
Write "Champ" on the front of the circle with the marker. Duct-tape the circle to the poster board belt.
Have your child put on the shorts, socks, sneakers, robe and champ belt. Drape the gloves around his shoulders, then wrap athletic tape around his hands. For the Rocky Balboa look, add a black eye with face paint.
