I got the pleasure of working on Elsa for the "Olaf's Frozen Adventure" Christmas special. I was responsible for all of the look dev and grooming. Her dress was a challenge- we ended up using xgen to create every little hair to get the genuine velvet feel. The fur around her collar and gems probably took the longest though...I did a timelapse to show the dress progress. Noone works in a vacuum though, thanks to the rest of the amazing team that helped with this character.
