The absolute best show this season by far was Saint Laurent and, like vogue28 said, reminded me why I love fashion. It was just perfection in every way possible. In addition to the clothing, I feel the setting, music, lighting, and casting all came together to enhance it all. I simply adored it all.
As for others, i loved Dries Van Noten, Lanvin, and Givenchy this season. Really wanted to like collections from other cities, but there was nothing spectacular. Paris just reigned supreme, but that's not saying much in this current state of fashion.
