Yes, it's just cosmetic now, so wear what you think looks nice!
I know this probably sounds stupid and all, but how about adding a cosmetic equip menu, and a regular equip menu, the cosmetic equip menu would show whatever you have on the cosmetics over the regular equips, its probably not that easy, from my limited understanding of this you would have to make multiple of the same equips with stats of other ones. but if you could find a way that would be really cool!
