She's Queen Cao(Cao Jie) ,who's Cao Cao's daughter and the last emperor's wife of the Han Dynasty of China.
so i remove the tag 'japanese clothes'

lol it looks like japanese clothes .. besides there are lots of scans where this tag has been added and I'd probably not think that way .. for instance there was some Reimu-scan (pretty colorful) - and it had the tag "japanese clothes" and I thought "wtf?" :X... well like I care.. I get the pic and save it on my hdd :p.

If she's wearing japanese styled clothing then the tag belongs there even if the character is not japanese. I'm not adding the tag back mainly because I don't know if that really is japanese clothing...

I think there are common roots between the traditional clothing of Japan China and Korea to some extent.

It's not just what you think; it's quite obvious. And one can also assume that due to the many aspects of shared culture in East Asia. ^A^

The thighhighs are probably not traditional though :)

I didn't say they were. ^~^

china-lolita :p

For many reasons, one could tell this is not japanese clothing even without the historical knowledge.
For one thing, the flower on her head is symbolic to China. It is on the tail side of the Chinese 1 Yuan coins.
The thing around her waist is also slightly different from its japanese and korean equivalent. To me, her clothes as a whole bares a lot of resemblance to the chinese girl characters from Code geass but I may be wrong. Check out Taiwan, Hong Kong, and China from Hetalia Axis powers for something very close to this fashion.

She may be 曹皇后 (a daughter of 曹操) searched from the copyright.

I'd say this is a kind of cross cultural style. I never see thighhighs in traditional chinese clothing, but that sword is definitely chinese sword.
