Hey there,
Could you please confirm whether you purchased the Birthday Barbie outfit directly from the Vending Machine or just used Nemo Bucks to exchange for Treats?
If you don’t have enough Treats, you’ll need to use Nemo Bucks to exchange for Treats first, and then use the Treats to purchase the outfit.
Besides, if you purchased this outfit, you will find it in you Locker.
Thanks for your understanding and support.
