What is the Most Important Part of Final Fantasy VIII Quistis Trepe Cosplay?

As for the Final Fantasy VIII Quistis Trepe Cosplay, what is the foremost part in your mind? Is the Quistis cosplay costume or the wig or the accessories or something else?
As the instructor at Balamb Garden, Quistis has high ability and is thre youngest member of SeeD at the age of 18; as a result she attracts many of her zealots who set up the Trepe Club because of her special charm. In fact, she posseses both good personality and professional competence, meanehile, she is quite self-possessed and perfect. On my part, she is really an outstanding lady as well as a great cosplay choice for girls.

    Generally, her accoutrement is in the form of a pair of glasses, long brown hairdo, and the suit that fltters her good body shape perfectly. And in my opinion, the most important part of the Quistis cosplay is the hair and the wig, if you just wear the Final Fantasy VIII Quistis cosplay costume in the show, and probably most of the participants can’t recognize you at the first glance. It is because that the same suit is not enough, there are so many famel characters from the anime, comic, video game and other media, and the suit is somewhat the same as the other roles, however plus the glass and the hairstyle, which is the unique figure among the tons of characters. Do you think so?
