Do you know which items are missing?

No need to post them. Have you done an account search to see if they are listed as in your wardrobe, or possibly somewhere else?

Do they show up in the old wardrobe?

Are you able to locate any of them (you don't have to check them all) if you use the option of "All Items on Subeta?"

You can file a ticket and a UA can manually remove them. :)

locking since the beta wardrobe is no longer on site
