in HEMA (aka historical european fencing), much of the sport is done with fencing masks on, so identifying your clubmates during sparring or tourneys is just based on gear. you know, what color their jacket and pants are, what patches they have on it, how is their mask painted. If someone borrows someone else's jacket it's legitimately jarring, like having someone with an entirely different body type and way of moving stealing your friend's face.
Once i read about historical fishermen in the north sea and how they each had a specific hat pattern that their buddies would use to identity them while they were bundled up. It was so much part of their identity that they were often buried wearing those hats. The gear is like your name, a visual identifier of YOU when you do not have a face.
anyway, back when I was buying gear i got my pants in ELECTRIC blue. I figured i was gonna get a black or grey jacket. but HEMA gear is kind of expensive because it's all custom- or handmade, so instead of spending $400 on a new jacket I picked up one secondhand for like 20. Except the only jacket that fit me was bright, SCARLET red. And I already had my expensive, new, custom, BLUE pants. I look like a damn rocket pop or like, a mixed Icee. I was like, shit! I should switch my jacket before i become the rocket pop guy!!!
Long story short, not only am I now the rocket pop guy, the color scheme has bled into my entire wardrobe. Every-fucking-thing I own is red and blue. I look like a french revolutionary. I look like a founding father in a school play. I have become a northern fisherman in my stripey hat. Now, even if I DO get a new jacket, I feel like I GOTTA buy it in red, yk? Otherwise they won't recognize me. Maybe I won't recognize me. I'm the rocket pop guy!!!
