When Anou is in a warm climate, she often sleeps in just her Sleeveless T-Shirt and her Goblin Apprentice's Pants.

When she is in a larger city, her sleepwear is more elegant and demure. The Imperial Red Robe, to me, looks like a silky nightgown with a loosely tied, delicate red robe over it. I know, blasphemy! ;) For those who agree but prefer a different color robe, there's always the Mystical Robe in purple, and a few other versions I think, namely one in green and one in blue.
