World of Warcraft’s Tyrande Whisperwind is a leader of the night elves and a high priestess among other things. Her appearance is striking, and cosplayer AllieCat captured it with a recent cosplay. She fell in love with the design and spent a month putting the costume together. She sewed the dress, sculpted all the latex details by hand (see a picture of a finished mold below), and cast the LED gems from resin. She used LEDs and other electronics to make the gems glow.
To make the bow, she created a template from paper and then cut it from foam board. She used expanding foam to add the bulk of the bow. She then carved the expanding foam down with a knife to the general shape of the bow. Next, she covered everything with papier mache and wallpaper paste to cover any holes. From there it was all about paper clay, smoothing, sanding, modelling paste, Gesso, and painting. She explains it all with in progress photos on her Facebook page.
