Thinking about killjoy jackets having meaning, which like, obviously, they're personalized, they're one of the things thats always on you, like your mask or your boots. But the thing is, even if you don't have a crew or anyone to watch your back, you have your jacket to. To quote something I read on here a long time ago that has stuck with me: "They say the Phoenix Witch can’t find you if you die without your mask on. But don’t worry, she knows your boots too. Maybe all that will be left of you is boots and a mask. That’s okay. A mask means that you were someone, a pair of boots means that you went somewhere." A mask shows you were someone, boots mean you went somewhere, and adding to that, a jacket means you stood for something.
I think a killjoy's jacket can tell a story. Look for the wear and tear, the laser burns, the patched-over holes, the parts that have started to fray. That alone can be a life story. Your jacket is wearing your interests and personality literally on your sleeve and being proud to show it, that you're there and you're alive and unique in spite of the world you live in. You wear your heart stretched proudly across your back, your destiny a mantel on your shoulders, and all your friends and all your enemies can see who you are and what you stand for, what you believe in.
There's so many different ways your jacket could come to be Yours. You find one one, make one, personalize it, but I think you could take it a step further, donning a dusted friend's or crew member's jacket is a vow, saying I will avenge you and honor your memory, and that memory, that legacy, that jacket becomes yours over time as your blood and sweat stains it instead, and the holes in it get patched with your colours now. Or maybe your jacket didn't used to belong to a friend, but an enemy. Maybe some killjoys take the jacket of the first scarecrow they stand against, fight and win, as a trophy, as proof to yourself that you're a survivor, you're a killjoy. Its a Fuck You to Better Living, its telling them my legacy with the grave of yours, its taking their sterile white and butchering it, tearing the city down in the form of personalizing your new jacket. Nobody in the desert wears white, but if you see a killjoy that is you'll know instantly its because they've fought and survived, and they're only wearing that white because they haven't had the opportunity to go buy some paint yet.
And then there's making a jacket for someone. A show of trust or devotion or pride above anything else. Its a love letter, a graduation certificate, a medal of honor. If someone's wearing a jacket that was made for them, then they've earned it somehow. It means you're worthy as a killjoy, as a friend. Wearing a jacket that was gifted to you, probably by an older 'joy, or a mentor, a friend, means they're dear to you in some way. You would die with their work, their name on you. It's wearing their heart on your sleeve right beside your own. Gifting a jacket to someone means you want that. It recognizes them as a killjoy, as a part of your story, and you of theirs, now.
A killjoy's jacket is a book, its both your shield and sword, its a legacy, and it can be a gravestone, or a curse, or a promise. Its you.
