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.
- Best<p> 18 April: Emily Blunt in Jason Wu at <em>The Five-Year Engagement </em>premiere at the Tribeca Film Festival in New York</p> <div> </div> <div> Hands down, one of the best looks we've seen from Emily, ever. This elegant cocktail frock with the green accents, combined with picture-perfect hair and makeup, is a winner.</div> <div> </div> <div> </div>

- Worst<p> 13 April: Zooey Deschanel in Stella McCartney at the world premiere of <em>My Valentine</em> in West Hollywood</p> <p> Zooey's bow-detail dress looks dangerously ill-fitting... </p>

- Best<p> 15 April: Kara Tointon in Alice & Olivia at the Olivier Awards 2012 in London</p> <p> The return to Twenties fashions this season may be one of the prettiest trends, but it's also one of the hardest to pull off without looking like a failed extra from <em>The Great Gatsby</em>. Kara's outift is a nod to flapper-era style but she keeps it fresh and modern. Gorgeous!</p>

- Worst<p> 16 April: Jaime Winstone in Giles at the world premiere of <em>Elfie Hopkins </em>in London</p> <p> The shaved-head look is challenging enough to pull off on the red carpet, so why Jaime would choose to team it with an ill-fitting dress that does nothing to flatter her figure is beyond us.</p>

- Best<p> 17 April: Leelee Sobieski in Jil Sander at the Vanity Fair party during the 2012 Tribeca Film Festival in New York</p> <p> A refreshing and simple summery look - we love.</p>

- Worst<p> 13 April: Kristen Stewart in Stella McCartney at the world premiere of <em>My Valentine</em> in West Hollywood</p> <p> Could KStew look more miserable? She's not selling this look, and the hair and makeup are a mess. Fail. </p>
