I never went to the "Through the Looking Glass" exhibition and I was not very fond of the idea of showing "fashion" in an "art museum." What is more, at the first glance, it seemed to be a celebration of Western designers' play with decontextualized superficial symbols of China (at Metropolitan, with the collaboration Maxwell K. Hearn? Hmmm.).
However, this catalogue justifies the exhibition to a great extent. Andrew Bolton, the main curator, was quite aware of Orientalism and the danger of that. He was not trying to show the real China, but the China imagined by designers and filmmakers: "Their China is one of their own making: mythical, fictional, and fantastical, it exists only in their minds."
Maybe this is a step forward in the development of exhibitions of non-Western-related themes-- historicizing the exhibits and bearing in mind that a single exhibition cannot represent the fluid and rich reality. What is more, it is quite up to date with the scholarly trend -- many art historians are now studying visual culture and fashion.
