Alexa Chung's book It was released in America this week. Of course the fact that I got it and read it a couple of months ago makes me feel quite smug and that my fashion fantasy book club may actually be real. So obviously, in between Halloween activities, Alexa has been out and about in New York looking amazing and stylish.

This was a bit of a departure. Sure, it is pretty consistently mod-style, which is very her. But it is floral. It is a delightful dress by Erdem that Alexa has Chunged-up to look effortlessly cool. So very successfully. And she knows it.

I also adore this trouser suit by Christopher Kane, with the embellishments at the waist and hip for evening pizzaz. This is obviously from the same collection as Kate Bosworth wore yesterday. And it is awesome, right?

And this look that she wore for the Teen Vogue Fashion University talk that she did last week. Full 50s style skirt with the leather jacket over her shoulders — right out of the pages of Grease the movie. Only not in pink. Love it. Am going to steal it. Which was your favourite look?
