Achievement Style Points (Equip a Cosmetic Armor)

[-V4NS]

I’m changing the appearance of the armor, but the achievement isn’t being credited to me. Has anyone encountered this?

[Shock_&_Awe]

I think it’s from the Valhalla DLC if I remember correctly

[Hotel Security]

Yes, there's a whole costume thing that replaces armor in the DLC. It's referring to that.
