If I hide my shoulders in my outfit my actual armor shoulders shouldn't show up. this would open up so many more Outfits. I do think they should reduce it to maybe 4 items can be hidden minus the helm so 5 total. Don't need fully naked people running around everywhere.
I love the outfit system too. Against my better judgment at first, I purchased an extra outfit slot for my main character, but I've found I don't regret it.
