Later in the game, you can reenter the copied city. I want to do this using 9S as there is a box in there only he can open. I've gone in, but it seems like in the area where you
fight Adam,
the machines lifeforms respawn endlessly and I can't find an exit. How do I get out?
Skins are listed as Key Items. Once you've redeemed the preorder codes for the skins, they will appear in your Key Items and you can simply equip them from there.
From this guide:
First off, bring up the game’s main menu and head over to the Items tab. Look for the Key Items option and select that. Here, you’ll find all the important items you’ve picked up over the course of the game. Select the skin that you want to equip, and then hit the Equip option. Once you do this, your Pod will assume the appearance of whatever you picked for it.
These chests are actually impossible to open as 2B.
However, after completing the story the first time and receiving ending A, replaying the game will have you play as 9S. 9S's signature ability to hack machines comes in handy, as he can use this ability to hack locked chests that were unable to be opened while playing as 2B.
During your first playthrough, since you can't do anything with these chests, just make a quick note of where you saw them and move on.
It's worth noting that this ability opens up a lot of previously unavailable side-quests, as well, in case you felt that there was a serious lack of side-quests your first time through.
