Since we're always on the lookout for great celebrity style, here's a round-up of this week's best-dressed. And since there are often fashion misses among the hits, we couldn't resist pointing out those looks that were better off left on the hanger.
Check out our latest installment to see which stars nailed it and who was a fashion mess. And don't forget to check back each week to see who made the cut.

- Worst<p> 15 January: Erin Wasson at the 13th Annual Warner Bros. and InStyle Golden Globe Awards after-party in Beverly Hills</p> <p> Note to Erin: Just because you posed nude in a professional capacity for your modelling work doesn't mean only wearing a thread of fabric qualifies as an acceptable 'dress' - ever. Especially not at the after-party for a major awards show, where people are wearing metre upon metre of fabric.</p>

- Best<p> 14 January: Rachel Bilson in Chanel at the Art of Elysium Heaven Gala in L.A.</p> <p> Sugar, spice and everything nice? That's what Rachel Bilson - in this Chanel feathered frock - is made of.</p>

- Worst<p> 14 January: Kelly Osbourne at the Art of Elysium Heaven Gala in L.A.</p> <div> </div> <div> The most worrying thing about this look - a miss from head to sack-covered toes - is that Kelly is usually the one to pass judgement on these types of disasters as a resident E! channel fashion expert.</div>

- Best<p> </p> <div> 17 January: Jessica Alba in Erdem trousers, an Acne jumper and Barbara Bui sandals arriving back at her hotel in New York </div> <br /> <div> </div> <div> If this is what we looked like when we walked around town every day, we'd be very happy indeed. Jess mixes stylish brights on top and toes with floral printed trousers fearlessly and flawlessly.</div> <div> </div>

- Worst<p> 17 January: Vanessa Hudgens in Amanda Wakeley at the premiere of <em>Journey 2: The Mysterious Island</em> in Sydney</p> <p> The black bra peeking out immediately brings this look into trashy territory and draws the eye to the fringing, which is also a bit too <em>Dancing With the Stars</em>-y for our tastes. The bag needs to be ditched, too. </p>

- Best<p> </p> <div> 15 January: Tilda Swinton in Haider Ackermann at the Golden Globes in Beverly Hills</div> <br /> <div> </div> <div> Tilda Swinton and Haider Ackermann - a match made in sharp-tailored fashion heaven. The stunning blue hue is gorgeous with her colouring, and we love the quiff. She easily took home the prize for best dressed at the Globes 2012.</div>
