So the weights on the jacket.. the original has some cool movement that's not possible to recreate. I tried transferring over the bones, but there isn't a male item in the game with that same skeleton to link it to. The original female bodysuit uses the skeleton for the Sphene jacket, and there isn't currently a male skeleton for that specific item in the game, so it's not possible to have the same movement [at least, not in any way that I know of] so the jacket is just weighted to the body like usual. If I ever find a way of getting that movement on a male item I'll update this, but for now this is the best I can do
