Suiting up is pretty easy once you have your routine sorted out. Having some of your parts on a table is very handy. Parts like the arms, gloves, helmet and blaster, all parts that go on after your torso really.
My routine is to put my thighs on first, then boots, then shins, then complete torso. I fix my belt and canister before I have my arms on so it is easier. Then I slip on my arms, then my gloves (tucking them inside the forearm) and finally my helmet. Job done!
