Costume Dress (霊衣開放, Rēi Kaihō?), also known as Costume Change, Spiritual Costume Unlock or Spiritron Dress, is a feature that lets any Servant (Provided that it has an unlockable outfit) to switch their outfits, other than the 3 Battle Sprites unlocked from Ascension. This was introduced since v1.25.0 with Mashu Kyrielight being the first Servant with an alternate outfit.
Each Costume dress requires a Costume Unlock Permit (霊衣開放権, Rēi Kaihō-ken?) or Wardrobe Key. these will allow players to unlock the costume once obtained it will never expire. if you don't have the servants for the costumes it will stay in the costume dress inventory. all costumes dress can be found in the Unlock Wardrobe (costume dress inventory) located at the very bottom of the Enhancement menu.
To obtain these Permits/Wardrobe Keys, you may have to:
- complete certain quests during events.
- buying them in event shops (usually after clearing the Final Main Quest).
- buying them from the Mana Prism Exchange in Da Vinci's Workshop.
- play through Main Story Quests (for example, Mashu Kyrielight's Ortenaus and Karna's Burning Garment of Three Gods)
Using the Costume Dress requires the servant to be at max level, exchange of materials and QP. For more information check the costume list below.
As of v1.33.0 the 
icon in the shop and event shops was replaced with a servants' portrait with a smaller costume dress icon to the bottom left.
