In Elden Ring Nightreign you can change the outfit (skin) of every character via the Dresser. This page has a showcase of all 40 outfits in the game. There are 8 characters and 5 outfits per character.
How to Unlock Outfits & Dresser
First, you must finish any two expeditions to unlock the Dresser. Then you can find the dresser in the easternmost room of the Roundtable Hold hub area. You can also select “Change Garb” from the map menu to access it instantly. You don’t have access to all outfits right away. They unlock gradually as you complete more expeditions, and all of them are available after finishing all 8 Expeditions.
