Why we love the androgynous look

I've been enjoying the androgynous or "boy look" for a while now. What is it about a shirt buttoned up with some tailored trouser? It's such a smart and satisfying look that is so easy to wear to the office. The SS12 shows show thus look isn't about to die, Christophe Lemaire, Givenchy, Hakaan, Gucci and Manish Amora as well as lots of others included androgynous styles in their collections. Not to mention the fabulous Katy Perry sporting this look with a 1940's twist on last weeks XFactor. Dressing like a boy has never been so HOT.
