Are your memefic characters stylish? Or not? What do they like to wear? Do they follow trends? Etc
I keep forgetting to lean into this more for Marcus/Kal. Marcus isn't fashionable in a following trends way, but spending stupid amounts of money on clothes was one of the few things he could make his own decisions about as long as it wasn't too flashy. So he's the kind of fashionable where if you Know he's obviously dressed very expensive, but following trends too much is for nouveau riche and not rich-rich. Cyril is also somewhere in this area after he gets engaged and his father in law starts trying to make him over, and Cyril is wildly uncomfortable with this because it mostly reminds him of Julius.
Kal definitely doesn't start very fashionable and by the time Marcus runs into him again, he's more on the flashy and scandalous end of fashionable. Right after Marcus buys him, Kal has an eye for what fits/what size things are/what's expensive after working in a laundry for a lot of his childhood but not really any sense of how that applied to himself. Then Marcus picked out his clothes and basically dressed Kal as an accessory to his own outfits so Kal never really developed a sense of what he liked himself.
Somewhere towards the end of the Kal POV part of the sequelfic, Kal will develop more of a sense that if he's going to be perceived he might as well decide how he wants to be perceived. He eventually settles on he wants people like Lucian and Marcus to perceive fuck you and trends more towards scandalous things like brightly colored socks, striped pants and plaid waistcoats by the time Marcus runs into him again. Lodee shows up in the big city dressed like he's still on the northern frontier because he's also performing fuck all this. Kal will eventually talk Marcus into something scandalous like flashy socks to go with his earring.
I don't have a good handle on women's fashion in this universe, but Mayke gets a kick about dressing extremely conservatively in some ways and then having a little flash of something scandalous or outre once in a while.
