Oh my heart. Imagine young Hux trying on all the uniforms except that one when he’s still a little boy, with the trousers pooling round his ankles and hands lost in flapping sleeves. But not that one, that ones special. And as he grows be tries the various ones on again and again. he’s 11 and over joyed when he fits into Captain (later Admiral) Piett’s uniform.
The day he tries on Moff Jerjerrod’s (weapons architect and his life long hero) old gear and finds it fits he wears it ever night for a week, pacing about his room and theorising how he might have saved the Death Star II. That’s when he first envisions Starkiller.
He finds a uniform that belonged to Grand Moff Tarkin when he was an Admiral and is amazed at 16 that it fits like a glove. He has his own uniforms tailored off that design and wears them with so much pride, not realising that whilst they share the same skinny frame Tarkin had a terrifying presence that Hux still needs to work on.
When he’s accepted to the officers academy he finally tried on the Grand Admirals dress whites. He doesn’t know who they belonged to but they’re wider in the shoulders and he ends up putting his spare epaulettes on the inside to make it sit right. And then he looks in the mirror and STARES because destiny is looking right back out at him. There’s the ghost of a laurel crown above the ears he’s not quite grown into, the white cloak turned Imperial red and the roar of an approving universe in his ears. He has all his uniforms remade, wears shoulder pads every day for the next fifteen years to keep that feeling off power with him every second of every day.
He keeps the uniform in his quarters on the Finalizer, in its own separate closet, and tries it on once a month, practicing his regal stride, the cloak spread wide behind him, murmuring kingly speeches to himself so he doesn’t hear the door open and Kylo Ren enter the room. He has no idea he’s there until he turns and finds him down on one knee, eyes turned to the floor and saber offered up in a promise of fealty to the Emperor before him. Kylo Ren is far smarter than people think, and he knows a truth when he Force shows it to him.
