Uh, they haven't at all yet but it's pretty early days. Jed lives out a boat so he's partially excused, the others might change outfits more often. I can think of two specific future occasions where primary characters will have to dress up for an event but otherwise creating an expansive character wardrobe isn't on my list of priorities.
I didn't go out of my way to design a unique palette for each character, per say, but they've certainly developed colour arrangements from which they can be easily identified. If there's a flash of blonde and brown for example, it's probably Serge. It's important to me that readers are able to identify each character at a glance (for continuity and flow purposes), but I also really hate overly complicated designs from a reader and creator standpoint as well. In the world of West, considering where the characters are and what they're doing, flamboyant clothing arrangements are inappropriate, but that won't always be the case. As and when the basic character designs do change, however, it generally denotes a much greater, over all change in that character specifically, as in something has happened to them and they are no longer the same as they were.
I remember that thread!! This was my contribution. It was a lot of fun.
