Wig is from ebay (I also use it for Tina, oops).
Head gem was purchased from ebay, then had the back painted for a deeper color.
The coat is hand-dyed microsuede, lined with quilt batting to make it puffy and warm! It's trimmed with an offwhite faux furwith a 2" pile.
The wings are a mixture of white and dyed teal feathers over a felt-covered wire frame. I plan to revisit these, as I'm not fully pleased with them (I was sent far more right-wing feathers than left).
As the costume itself was fairly simple, I tried to add interest with more outlandish makeup. I mixed white greasepaint into my foundation to make my skin more pale and frostbitten, contoured my cheeks with a teal tone, and went for very dramatic teal eyeshadow with a strong cateye. I also glued glitter to the eyes, cheeks, and lips to further enhance the frost effect.
