Formal Wear (30 days) for Appearance?

As title says, im wondering

Can you use the Formal Wear (30 days only) and the NCCOIN Armor Appearance stone to make my armor look like formal wear?

or do i have to get the permanent formal wear to be able to do this?

If anyone can answer my question,

Thanks!;)

no you can't, you need a permanent formal wear.
(i tried it already xD)
