Yes! There's an appearance window under "C" your character window, at the top middle. Theres a green armor icon you can click, then there's a list of numbers, you probably only have one, but if you click the one that says "1" you will open appearence tab. Then you can right click armor you have in your inventory and then press "apply" (it will cost you credits) and then you can click "activate". Then you will look that way, even though you have a different armor.
Best wishes, and welcome back friend! π
