Gross can be described as, "To be fill with disgust; nauseate" If your looking for some gross costume ideas to freak out your guest at your Halloween bash, check out these sick costume ideas:
Green Slime Costume
Nucellar Fallout - By Gary Green
For this costume, you want to send the message that you are not only slimly but deranged form nucellar fallout. To start, go shirtless (ladies, feel free to wear a sports bra.) and wear shorts.
Using green body paint, apply the desired amount to your body and face to create the effect that you are oozing form radioactive fallout. If you really want to get creative, add actual green slime to the paint, to make the costume all the more realistic. If you want, utilize some red body paint and drizzle throughout the green for the effects of blood.
Pus Face Costume
Unfortunately, our model had a in a horrific skin condition on the day of her sexy girl photo shoot; however it worked out ok - it gave us a good idea for a gross Halloween costume idea. For this costume we need to create the fake pus-filled blister. Here, buy a bag of gelatin powder (always available in the baking aisle of any grocery store) and a small bag of glycerin (usually found in the pharmacy section).
Mix 1 tbsp. of gelatin with 1 tbsp. of glycerin and a half tbsp. of water in a small cup. Then microwave the mixture in 5 second bursts until it is liquid. When hot, mix in yellow / white food coloring and pour droplets of the mixture onto parchment paper. Once cooled, use body adhesive to glue the pus droplets onto your face. Be sure to get creative with some fake blood to hit home the idea that these are extremely painful blisters.
Creator Face Costume
Dark Side of The Moon - Ray Armstrong
The gimmick for this costume is to have a face just like the moon (with lots of creators.) To start use thin layers modeling wax, apply it to the desired areas on your face. Next, use the head of a screwdriver to poke indents into the prosthetic / wax. Use red food coloring or another form of fake blood to fill each indent. Be careful at parties, this costume is so realistic you may even scare people away from talking to you.
For a bleeding gum effect, you can always buy a 10 pack of fake blood pills from your local Halloween store and periodically place on in your mouth and chomp down for some bloody fun. However if that's too much, you can always buy fake blood stained teeth as well.
Worm Face Costume
Blood Sucker - By Beverly Sims
Imagine signing up for experimental treatment study on skin repair cream and you leave with bloodsucking worms stuck to your face, draining your blood by the second. For this costume, you want to make it as gross as possible.
To start, you need to purchase a small jar of modeling wax, which forms to the skin like a prosthetic, available online for under twenty dollars. Slather it around both orbital bones, leaving out a hole in the middle (this, of course, is for your eye.).
Next, using body adhesive, glue each prosthetic to the left and right side of your face. Now, we need to make the worms. For this part, buy a bag of large sour gummy worms and place them in a bowl. Using a pink or red spray paint, color all of the worms to resemble the actual insect. Once dried, glue them onto the prosthetic that has been applied to your face. Feel free to get even more creative, such as spraying fake blood throughout the rest of your face and neck.
