The 52 must-see looks of the week

New looks are everywhere this week. Rihanna is now blonde, Katy Perry has gone for blue (hey, who hasn’t done something wild with their hair post break-up), and Kelly Osbourne finally explains what the grey hair was all about,

“I’m 27, I’ve got three years left, the way I look at it, to have fun with [my hair color] because once you’re 30, you look like a right idiot walking around with like rainbow, bright color hair and all different things like that,” she said in an interview on her mum Sharon Osbourne’s show, The Talk.

Talking fashion looks, Sofia Vergara and Rachel McAdams are rocking sheer tops, Rihanna stepped out in a double denim jumpsuit and in an awkward wardrobe snap moment, Rachael Taylor and Jodi Gordon both wore white sheer, long-sleeved dresses to the movie premiere, Any Questions for Ben.

But first let’s start with the hottest looks and trends from the Annual Academy Awards Nominees Luncheon in LA. The Oscars are on Feb 26 – mark it in your diary – and today the nominees met up for a sandwich.
