Any type of shorts will work for this. A comfortable pair of cotton shorts are ideal, though. The smooth fabric will closely resemble a store-bought Bam Bam costume.

Cut a few holes into the waistline and thread a string or piece of twine through the waist to make a belt. Wear shorts underneath your half-tunic just in case the string breaks.

You can sew the triangles into place if you really want to, but hot glue is pretty good at bonding small pieces of fabric. Don’t forget to do the back of the half-tunic as well!

For a different look, you can wrap the shoulder strap fabric up by twisting it to make it thinner and pin it in place this way. If you do this, pin the twisted fabric together on top of your shoulder with a safety pin to keep it from unraveling.

The easiest way to draw a bone is to draw two parallel lines and put two overlapping and symmetrical circles on each end. You can always pull up a drawing of Bam Bam online and use it as a reference if you’d like. If you’re good with a sewing machine, feel free to cut out 2 bones out of fabric and stitch them together. When you get halfway around the bone, stuff half of it with cotton fluff. Continue stitching and stuffing until you have a plush bone.

Bam Bam is traditionally shirtless, but you can throw on a white T-shirt or tank top underneath if you’re heading out for a party or Halloween. Use brown sandals or sneakers for the shoes. Bam Bam is usually barefoot, but this is obviously a bad choice if you’re going out for trick-or-treating or a costume party.

You do not need to make the hat if you don’t want to. The half-tunic and the bat should be more than enough for most people to realize that you’re Bam Bam. If you used a different color for the half-tunic, use that same color for the hat. Bam Bam’s hat and half-tunic always match.

The triangles that go on Bam Bam’s hat follow the same general shape and pattern as the half-tunic, but they’re usually half of the size.

Don’t forget to cover up any logos or writing on the hat.

You’re going to cover the tissue paper, so don’t worry about the tape showing.

Felt is better if you want a softer looking bat. Paper is ideal if you want some texture in the bat that will vaguely resemble wood.
