I made a few of my own bodysuits to take the place of paint, but I hated that there was a seam along the side of my body and/or legs. This is fine for Spiderman or another character who wears a tight-fitting suit super hero suit, but a couple of my characters have skin tone that is not flesh tone, and a simple body suit was a quick solution when I want to wear say, Midna, but didn't feel like spending 2-3 hours on make up.
This suit would also be good for Avatars, Shiva from Final Fantasy, Night Elves and any other number of revealingly dressed characters.
The motivation of creating this tutorial is to help you make a body suit even if you don't have a firm grounding in using a sewing machine. You only need a straight stitch and a zig-zag stitch for a wide neck suit. If your suit needs to be closer fitting at the neck than Midna, you may need either a zipper, snaps or possibly just an elastic band or velco in the back, if your back will not be visible while in costume. If your back will be visible and you need a close fitting neck, you're stuck with a zipper, but you do have a few placement options depending on the character - You might luck out and be able to put a seam on one side under clothing or put it in the lower back to leave the upper back zipper free . For the truly hard core, you can put the zipper along the *ahem* derriere, assuming that that is the only place that won't be visible. This is even doable if making an Avatar, since you'd have a tail - it's just a matter of how dedicated you are to having as few seams visible as possible. (I have not done one of these)
This tutorial will only be covering a basic bodysuit - no hands or feet - for beginners who just want some smooth lines. Personally, I'm rather anit-covering hands and feet because gloves and a single toe foot covering just break the illusion that much more. These suits are all about maintaining as much of the illusion as possible.
With Midna, I studied a number of screencaps and finally determined that she is actually topless. Her only clothing is a skirt and cloak, and her skin is dual-toned - both black and pale blue. Her skin is actually more black than blue, but starting lighter and painting darker will work for you better than starting with black fabric and painting light on top of it. I didn't saturate the black as much as I could have on the body, because I think it adds to the look of having dual-tone skin.
Since my body suit ended up 2 colors, I'll cover painting later on, but you may not need it.
if you need to dye your fabric, do so first, before cutting. I was lucky enough to find this fabric on ebay, in the color I needed. Rit dyes and Jaquard acid dyes work equally well.
Needed for this project:
Four way stretch fabric - Lycra, spandex or in that family
Scissors or Pinking Shears
Knit or medium weight machine needle
Lots of paper
Fabric INK (not paint)
Sharpies of your color choice
Bodysuits are more flattering than bare skin, can give you a better waistline, smooth curves and it allows you to wear shapewear underneath ::cough:: should you feel the need to do so. It's even possible to make a fake bellybutton. They're fast and easy to get on, and it's simply a matter of matching paint to your skin. Additionally, you can wear a push-up bra or other bra under a bodysuit. Pasties do nothing for support, just sayin'. A suit makes it easier to cross play - a male cosplayer can have fake boobs with little extra effort and a female can bind securely and the suit can still be nice and smooth.
Cons: no matter what you do, it will not look like real skin - but it can still look great in photos - and looks a lot better than smudged or fading paint. In my case, I don't mind the extra 'help' smoothing out my curves. Another con is that if you snag part of your suit, you have to either repair it or replace the entire suit to maintain the "seamless" look. One good sized frayed snag will ruin the illusion. Another disadvantage comes with bladder control. You must have it for most bodysuits. I can go 5-8 hours in this and not need to pee, as long as I don't drink anything.
