I used 0.35mm white latex for the garments and a thinner 0.18mm black latex for the ruffles and the trim. The trim is cut using a wave form rotary cutter.
The polka dots are hand cut from 0.35mm bubblegum latex.
I also made a neckband in the same style saying "Do you still love me?" that never made it onto the pictures of Erika. And yes, all letters are hand cut and glued to the neckband with patience and love ;-)
