So I spent $10 and got 6 treasures from Eververse. Out of the six I got 2 DoI ornaments, which was really cool. I was stoked to use one and I only had the chest, legs, and arms so I put it on my chest. Now I have zero ornaments left and I'm not sure if the chest piece takes two or if the game just used both up? I assume it only needs one ornament so I'm a little upset that the game used up both of them :( (Be careful if you have multiple in your inventory!)
