You don’t need to. It’s just that you describe very specific outfits right now. You could also just describe a general style instead that leaves the mc more room by default for players to enter their own headcanon.
In my humble opinion @Snoe 's old WIP: “Freak: Amidst the Neon Lights” does that really well, giving general styles, instead of specified outfits for the mc to pick from in the shopping section.
The other option that I’ve also seen used once or twice in WIP’s is to have one of the choices be for the player to just enter their own description, like a character name, but for clothes instead.
