Here’s a random question

Is Sailor Moon wearing armor or is she actually wearing a white leotard?

I always figured it was magical, body-conforming armor, but every cosplay I’ve ever seen usually is a white leotard….

I wonder if that’s just a common cosplay choice because of physical limitations in fabric ( aka magical armor doesn’t exist in RL) or did I miss some explanation/scene that shows the white part being actual skin-tight fabric?
