You could describe Phenomenon purely in terms of avant garde design and deconstructed aesthetics, but to limit such a playful approach to fashion to industry language, is to miss a great deal of the point in what Phenomenon does, which is presenting classic garments that are recognizable, but feature an unexpected twist.

To have an opportunity to bring this to life is not something to pass up.
