Not sure if Bug or. . .
with the character(s) that last had the outfit, find the Black Lion Trader (Armorsmith) – they’re usually near the Black Lion NPCs. when you talk to them go through the town clothing option (What are town clothes? >> So what do you do with town clothes? >> I’d like to exchange my old town clothes. >> I’m ready. Upgrade all my town clothes.). this will give you an item in your bag that you can click to add to the wardrobe, or a tonic, depending on the outfit.
hope that helps

The outfit is the Witch and Mad King outfits. I purchase them several years ago. But they are locked in the outfit tab.
You should find an item in your inventory to consume (double-click) and unlock the Outfits, after speaking to the NPC.
If you continue to have issue, you can contact the CS Team via the ‘Support’ link above/below and ‘Submit a Request’ for assistance.
Good luck.
