I just have a question about older Eververse items mainly the armor:

So I’m a collector. Literally half of my vault is full with items that came from Eververse. Ghost shells, shaders, armor, bikes, the works. From reading the changes that are coming this fall I need a quick clarification. From what I read, if I have the item in my collection, I can purchase it back for glimmer and shards. And when it comes to armor(my real concern) if the armor is in my collection, I will automatically unlock the transmog for it. Is that true or will I have to have the item, THEN DE it? I’m wondering so I can get my Bright dust loaded up for the new season. Thank you for reading and helping me understand.
