/cgl/ - Cosplay & EGL

I love this design so much but I think making it is going to kill me. My main problem is the bodysuit. Most people modify it into a vest/bikini top and skirt and the one attempt I've seen at the canon outfit has sad saggy edges.
How would I keep the inverted scallop shape of the edges and frill and attach the forearm/calf fins so they won't make anything sag?
For the different coloured sides, should I use another fabric, paint it, dye it, etc.?

... Are you going to Otakuthon by any chance?
Go the lazy way and just cut hearts out of yellow craft foam. Looks more like a necklace to me than a part of her collar tbh and fabric might look weird.
