This is why I'd like to see transmog or cosmetic slots. It wouldn't be that difficult for Bungie to implement an extra set of equipment slots that are cosmetic only, could even let you directly equip from a screen like the Collections tab. Add a cost, glimmer would be ideal since they'd just be visual. If they wanted to be greedy they could add a new material, à la Guild Wars 2's transmutation stones, that can be recieved from Eververse engrams. It also kind of sucks seeing 80% of people in the same armor sets.
