I'm not sure either the only armor I've found is temporary armor which is the reactive armor I think that its temporary because it has a certain durability so it will break after a while so I wouldn't recommend you to keep buying those because its a waste of resource as for the permanent armor If theirs one for Sasha and your other girls I still haven't found it. Maybe try exploring more galaxies and doing more of the main story until it unlocks?
Yeah, your girls are stuck with their default armor it seems, and you can't change it. Then what's the point of the body equipment is that a form of armor of something else entirely?
