The flight suit itself was a Man of War two piece suit that I dyed black. The flight suit takes dye amazingly well. For the flack vest I ended up ordering from Krypton Top on Etsy and ordering black specifically. The material of the vest didn't dye as well as the flight suit, but I later learned about "synthetic dye" which might've worked better. Hope that helps!
ps. I also re-did all of the armor, helmet, gauntlets and jetpack in matte black. Really like the updated look:
