Find a corset that fits. Sewed the front clasp closed. Added on about an inch of fabric to the top since I didn't like how low cut it was.

(Not pictured here because I forgot to take a photo). Painted the corset with watered down acrylics. Mostly a light blue base, that way anything not covered with sequins would look okay. (You can use watered down acrylics and it wont crack. )

Get mylar sheets and cut into desired rectangles. Super glue for plastic is a must but needs to be used IN A WELL VENTILATED AREA. Im serious, some of them use toluene. Get a mask, work outside. Dont do this indoors!

Layer to your hearts content.
