Wow. Thanks for sharing. How interesting.Chock has been very involved in the design of most of C/B's costumes, including the snake dress. A FanZone article gave some details as to how Madison and Mathieu collaborated on the FD costumes :
"Chock literally studied images of snakes—their scales and patterns—to come up with ideas for her dress. She wanted her dress to look like a snake's skin, but not like a snakeskin fabric. She brought drawings to costume designer Mathieu Caron, who made sure it was functional while also creating wow moments. "Together we came up with something beautiful," said Chock.
For Bates, Dubreuil envisioned a turtleneck shirt. Chock found the braiding technique and showed it to Caron, which he incorporated. "
