Windows 2000 has always been my favorite OS in terms of design and ease of use, and the 2chan personification almost always appeals to me.
I based my swimsuit pattern off a vintage swimsuit with a modesty panel from a local reseller, and the jacket was a combination of several patterns (for the top shape, sleeves, and length). The boot covers were made by pinning the material snugly around my leg and putting a wedge shoe on after, then securing the bottom of the boot cover.
The "ears" are made from craft foam and covered in epoxy resin, while the "crown" between them is cardstock.
The wig is a heavily trimmed Electric Blue Femme Fatale from Amphigory.com
