Analogous to Wa Lolita, this is a "traditional Japanese maid". It usually means a yukata or a relatively simple kimono with an apron. The maid headdress is not strictly required, though it is often still present. A classic example is Tsukihime's Kohaku.
If a Western maid outfit is also present in the image, tag mixed maids.
