Another picture of Bernadine, for reference. She doesn't have one set outfit, but rather, a few different ones, all in the same color scheme. If you want to draw her, anything Steampunk, pirate-y, formal, and masculine in a green/gold/brown combo will work.

If you're so inclined, Bernadine now has a profile on Charahub, where you can see more about her! I'll be updating it more over the next couple weeks: https://charahub.com/character/366991/Bernadine-Schwartz/public/
