/cgl/ - Cosplay & EGL

I'd really like to do the space suit version of Bee, been researching ways to get the helmet visor exactly right and so on..
But I'm your average petite rectangle girl. I'm working out to get some curve and a butt, but I will never have nice hips. I'm super afraid I'll look like pic related (no offence) in a bodysuit.
Are there any materials that could possibly benefit my shapelessness? Are butt boosters/waist slimmers and whatnot worth a try and how much like a pillow would they look under a bodysuit?
