Cosmetic Slots
In the equipment menu, you could add Cosmetic slots that would just have the appearance of the item in the slot without any of the stats. Right now it's fun being able to tweak my armor to look good while still giving decent stats, but as I unlock more equipment, I'm finding a lot of gear that I really like appearance wise that don't work for me stat wise. So having the option to wear them for fashion would be a nice addition.
