I assume this isn't a ingame attire, right? (since the screenshot I saw she wears a suit)
Well... she is wearing a suit in the event recently (mainly because she is Gilgamesh' secretary) but no one says that she can't have a version with her green outfit and headscarf, no? I still pray to get her as a playable unit in the game. Pls DW!
Siduri's outfit for her (rare) days off After dealing with Gilgamesh all the time she needs some stress-relief and being a Priestess of Ishtar (aka the Goddess of Love, War and Madness) I can guess now she lets of steam XD
