This homemade costume for adults entered our 2014 Halloween Costume Contest, and won 1st place in the Coolest Adult Costume nomination!

A word from Klay, the 'Giant Squid' costume creator:

I fabricated the entire body from cross-linked polyethylene foam rubber that was glued using contact cement. The suckers are formed by heating foam discs and pressing them into a cup shaped mold. Thin foam is sprayed with adhesive and applied like wrinkles over the brow line.

The entire body is then coated with Rosco Flexcoat product and allowed to cure for 24hrs. Then it’s painted with a high quality acrylic paint (Sherwin-Williams). Holes are cut in various locations on the mantel and covered with mesh fabric to allow ventilation and visibility. Highlights and shading were added via airbrush to camouflage the holes. A computer fan was mounted in front of a hole in the top.

EL wire was pinned into the pattern shown using thin wire. The eyes are punch bowls from a party store with a round piece of black vinyl applied.

The pants are made by stuffing spandex leggings to pre-stretch them into the shape of your legs. Make sure you stuff them enough because the latex won’t stretch as far as the original spandex. Glue on additional suckers with contact cement. Then prepare a mixture of ~7 parts liquid latex (special effects supply) to 1 part high quality acrylic paint from art store. Paint this over the pants in THIN coats. If you coat too thick it won’t dry properly leaving you with a liquid filled bubble. You’ll get a perfect color matched finish that has a lot of flex and durability. Go over it with a watered down wash of black acrylic paint or splatter with off shades to get more depth.

Feet are fabricated from the same foam rubber while being heated with a heat gun. Then prime with Rosco Flexcoat and paint with the acrylic/liquid-latex mix. Again, do NOT confuse this with “latex paint” from the hardware store which will not flex, will crack, and give you MUCH worse results. The finished shells are then glued to scrap shoes using contact cement. This must be done or they will shift around and be very uncomfortable.

My first thought was literally "Yaaaas." Excellent work! I've never seen a giant squid costume before! I love how you turned your legs into tentacles. What a brilliant idea. I love it!

Fantastic! What keeps the tentacles flowing? Wire?

I love your costume! Do you still have it and can it be rented by any means?
