I've just ripped the DLC costume Artworks from the official site. All of the characters get one and it looks interesting because the theme is school.....
Shu looks low-profiled, Wei has this royal'ish like, and Jin looks like rich people =p
I think an anime based on DW7 DLC costumes would be cool. A rivalry among the 4 schools hehehe.....
Here's my favorite DLC costumes from each kingdoms.....
Shu: Jiang Wei, Zhao Yun, and Xing Cai
Wu: Xiao Qiao, Sun Shang Xiang, Lu Xun, and Zhou Yu
Wei: Cai Wenji, Cao Pi
Jin: Wang Yuanji, Sima Shi, Sima Zhao (I like their costumes the most ^^)
