Yes! (Time For A Costume Change!)

You decide that although it may be a tiny bit risky, putting on the armor would increase your chances against anything that tried to hurt you.

You quickly look around to make sure no one is looking before stripping off your leather armor in the hallway. As you slip out of each tight piece, the cold dungeon air slightly stings your bare skin. It makes your nipples become erect and hard causing you to rub your fingers across the tips. It feels really good and turns your cheeks a bright pink red. You're glad no one is around to see you act like this. You finally pick up the armor and unhook the straps to find a keyhole lock on the belt with a key inside. This raises your suspicions, but you still decide to put the armor on. You twist the key in the lock, unhooking all the bindings and straps at once, making it much easier to put on. After you slide the chest pieces over your head and latch on the ankle braces, wrist braces, and metal bra you are now completely wearing every piece of the set. The metal actually feels a bit warm on you despite the chill of the area.

You've put the armor on, but all the pieces still remain loose on your body. The only thing left is the key. You know using the key will lock the armor together through straps, magics, and basic tumbler systems, but you don't know if you can get out of it if you loose the key, and who knows what enchantments might be triggered when it's locked.
