Beside's Seulbi's pink dress and Yuri's black and red dress, none of the costumes looks appealing to me. I hope they release new costumes asap.
Gotta love everything Seulbi wears <33333
There's a bunch more costumes that are not in the cash shop.
-The school uniform, gotten from the 50k NX box
-A recoloured version of most sets that you can only get through upgrading a different colour to a 3-star rank.
Wouldn't be surprised if there were other things.
Teleia - Level 70 Caster
무한의Hope - Level 61 Witch
