Clipmark

The only raw materials that you will need are an umbrella and a hooded zippered sweatshirt. You will also need some tools and supplies: needle and thread, pins, pliers, scissors, and something to cut the umbrella ribs, such as tin snips, bolt cutters, or cutting pliers.

Unscrew the top of the umbrella.

The cloth part of the umbrella with the ribs attached should be separate from the stem now. Clip off two ribs opposite each other, and save them for ear frames.

Pin the umbrella halves to the sleeves and sides of the sweatshirt, starting at the armpits.

Here's the gap where the ribs stick through. This will give you some flexibility of movement when you're wearing it.

Take the two extra ribs and trim extra points off so that you can make a (very uneven) tripod out of them.

You'll need someone (or a wig frame or mannequin head) to help you with this part.

After getting them nicely lined up, stitch them on and then trim off the excess fabric.

safety tip: Do not attempt this with your new costume.
