Tutorial by Vickybunnyangel
If you need to make fake boobs for whatever reason, we wrote up a tutorial using Varaform. You can alter the length/shape of the breast form to suit your costuming needs. I settled on an open chest with a high neck for costumes like Dragon Sorceress Zyra (League of Legends) and Night Elves (World of Warcraft).
Varaform takes complex shapes and curves very well which has made it popular for creating large-scale hollow shapes for theater and movies. Are you familiar with that trapped heat/sweaty feeling from wearing Worbla armor all day? The Varaform mesh allows for better air circulation and lets your skin breathe more. I wanted to showcase how Varaform can be used to duplicate a form, and we happened to have a mannequin around, so I made fake boobs!
1x 13″ x 19″ sheet of Varaform
Bowl of water
4-way stretch Spandex close to the skin color you want
Fabric-Tac/Spray Adhesive/Rubber cement
Preparing your Positive Mold
Wrap your mannequin with cling wrap with tape to hold it in place. Varaform is covered in sticky glue, and this makes it easy to take off of the mannequin once cooled. Use tape strategically to get the cling wrap to stick to the curves and crevices as close as possible.
Forming the boobs
Heat the sheet of Varaform on parchment paper. It will stick to the paper initially but you can peel it off easily. While it’s still on the parchment paper you can press it onto the mannequin just to get it to stick. Loosely stick the Varaform to the mannequin and peel off the paper. Then use your hands to carefully stretch it over the form. Make sure you wet your hands before touching the Varaform directly!
Take your time to stretch or compress the mesh as needed to get it to take on the shape of the boobs. You can always reheat areas with a heat gun if it cools before you can finetune the fit. Varaform is very forgiving. If you accidentally bunch up too much you can squish and flatten it down. No need to cut darts. Let that cool completely before removing it from the mannequin.
Draw your cutting lines while it is still on the mannequin. Think about what makes sense in terms of hiding the seam lines with your costume. When you’re happy with the shape, you can take it off the mannequin and cut away the excess Varaform.
Covering the Varaform
Carefully cover the Varaform frame with 2 layers of felt. I used a hot glue gun because it was quick. Felt can stretch over curves to some degree, but you will need to dart it at the side to get it completely smooth. With a single layer of felt the mesh texture was still visible underneath, but a second layer of felt covered it completely. The felt will also give your boobs a soft plush texture like skin.
Estimate how much spandex you will need to stretch over the boobs and use a good adhesive to bond the spandex to the felt. I use Fabri-Tac because it stretches well and can be spread thinly. You don’t want to use a hot glue gun because the hard glue trail it leaves behind can be seen under the spandex. If you have rubber cement, or want to to use tacky spray adhesive that will probably work well too. Starting from the middle, carefully stretch and pull the spandex to cover the boobs. Make sure you cover every inch in glue to keep the stretch fabric down!
Painting the Boobs
If you have an airbrush, this part will go by much smoother! You can get an even coverage and do subtle shading without any visible brushstrokes. The nude spandex was no where near my actual skin color so I had to get creative with the acrylic paints I had to make something close to my skintone. You can also buy airbrush paint that’s already a match for your skin, but I was on a budget so I used regular acrylic paint and Airbrush Medium to create my airbrush paint.
Mixing tips: You can see from the swatches that I struggled a bit before I got a color I was happy with. Everyone’s skintone is different so I can’t tell you how to mix for your skin but I used a combination of cream, brown, red, peach, and green to achieve mine. Green neutralizes the redness in paint very well and actually was the secret ingredient to getting something close enough to my skin. Make sure you mix up a lighter shade and a darker shade for contouring/highlighting as well.
Painting tip: airbrush different layers. I started with a more pinkish base because my skin has a slight pinkish undertone to it, and then I layered the more tannish cream color on top. This variation in color makes it look more skin like.
The finished boobs above! You can see that I added highlight and shadows to exaggerate the shape more and give them dimension.
P.S. I am very small chested so this is all held up entirely by the rigid under-structure of the Varaform.
Attaching the Boobs
Depending on your needs you can sew shoulder straps, or create a halter neck strap to hold the boobs in place. You can also cut up an old bra band and use that to attach the boobs around the back.
I hope you found this tutorial useful! There’s many other ways of course to create a breast form but we thought it would be fun to try it with Varaform.
