Coming Back: all racial/dungeon items gone
The wardrobe system would only grandfather in two things in terms of the skins/transmutation stones when it was first implemented. The item that it originally was stat wise and its skin and the skin you are now using. So if anything was used in-between and then overridden it is lost.
For example, I made a Berserker Ascended Staff but I also made a Knight’s Ascended staff to just use the green skin for it. Before the implementation of the wardrobe I decided I was tired of it and switched the skin to Ancient Walking stick. When the wardrobe was implemented I had the red Berserker staff skin and the Walking Stick skin. The green staff skin was lost because the game had no way of recognizing that I had ever owned it.
And yes even so the culture armor works the same. Even though the style achievements log that you did buy something to get credit for them.
The wardrobe would pick up skins for items you have soulbound but still in the inventory, items you salvage, or right click and add/unlock skin to the wardrobe (making it soulbound).
So even if you bought these items in the past and ended up not using the skin anymore they are lost and you have to unlock them again.
If these items were active skins you were using on your characters and now gone though. Then I’d say contact support by submitting a ticket.
