Item appearance not added to wardrobe

I have just purchased 3 or 4 items from the darkmoon fair and equipped them on my character (yes its correct armor type) and they are not adding to my wardrobe

Did it show up in the collection on the character that learned it, just not alts? If that’s the case, it can take some time to show up. Usually the refund timer is the biggest issue, sometimes even if equipped. You can try favoriting the item by right clicking in the collection or transmogging it on the character that purchased them as that sometimes breaks the refund timer issue and forces it to show up.

Or did it not even add to the collection on the character that learned it, either? If they were replica items, you must learn it on the class it’s meant for, then it will show up for all characters of that armor type. When you purchase the devout replica set, for example, it pops up that you must be any of the priest specs to learn it. Once I learned it on my priest, I believe my warlocks and mages could see it in the collection.

No nothing, i searched the item name in my collection tab it was still grayed out

What item were you trying to learn and on which character?
