RPG SITE REALM REBORN INTERVIEW

Costumes are usually cash-shop with special items made specifically for that slot, that you pay for.

I've never seen anything different in ANY mmo I've played.

In Aion it was just copying the look of a gear other another gear. But only gear of the same kind.
Clothes to clothes, leather to leather, chain to chain and plate to plate.
And no cash item was involved.

Just because they add vanity slots does not mean they have to allow anyone to wear anything. They could still keep level/class restrictions if that was to be an issue, not that it really is an issue in the first place.

This.
SE could keep the level/class restriction in the vanity slot intact.
A BLM can then wear a Felt Bliaud for the stats and Coliseum Shawl for the look, but he can't wear Vanya Robe for the stats or look.
