I would say that fashion is 90% of what all my comics are about. Usually the first things people say about anything I draw is "I love the clothes" or "OMG the fashion" which just motivates me to come up with new clothing designs...
This is one of my earlier drawings of my comic cast, so some has changed. Nox on the far left dresses cheaply because he's always broke. He only wears black or white, and his clothes tend to be slightly shredded. His hair color changes a lot but always covers an eye, and usually tops off the look with a ton of smeary makeup. This picture has a really early version of my girl Savoy, where she had a real 80s porn star look. I wasn't happy with the whole bleach blond leopard print thing, so now her look is more rock-chic with lots of shreddy black clothing, bleachy streaked black hair, garters and shredded tights and lots of leather. She and Nox tend to dress alike with hair and clothing, which is why they hate each other (looking in a mirror is hard, haha)
Here they are together- my only color picture of my current design for Savoy, oops.
Fabian (with the pizza) always wears much more expensive clothes. Lots of ruffled shirts and fancy hats. He always has tight, well tailored pants and goes for rich jewel tone colors. He doesn't appear too much in the comic, and usually has obscured feet thanks to playing drums, but he definitely wears expensive leather moto boots. He also wears a lot of fingerless gloves just because he thinks its cool for some reason.
Roy starts off the story with a very effeminate look- lots of teased hair, jewelry and skirts and dresses. But his look changes dramatically and starts going for a military/40s/leather daddy kind of look with lots of tattoos and body mods. It shows his interest in discipline, honor, brotherhood, and kind of represents a lot of looks in the gay club scene of the time. Most people that have seen my sketches of him know him as 'that rubber singlet guy' ... Pretty much he dresses like a gothic Tom of Finland picture. He's the most likely to wear assless chaps. His colors of clothes are olive, gray, white and black, though its more likely to vary with some autumnal 70s colors as well.
My compare-and-contrast Roy, from first chapter to where most people have seen my sketches of him. His fashion choices probably show the most growth throughout the story.
Every chapter I really think about how my characters have changed and where their fashions are going to reflect this, plus I think about what year the chapter is taking place and how the looks should reflect it. My current chapter is still very early gothic/punk inspired, but the next chapter is going to take a turn into early industrial fashions, a bit of bondage inspiration and 80s Asian-inspired cultural appropriation crazes. I could probably talk about clothes FOREVER and I love giving people outfits for their characters- so I've gotta stop here!!
