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 instalment 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.
And this week, all our winners are in Paris Fashion Week designers - it's our way of saying, au revoir until next season.
Best & worst dressed of the week: 12 March
We can see why she's Karl's new mademoiselle. Lively looks stunning in this silver sequinned and ruffled dress. C'est magnifique!
Sorry, Mel, but this dress is more tart than sweet: the frock's hue is a garish yellow (and doesn't need the floral detailing, either), the booties are tacky and don't match and the extensions look fake. Miss!
This is a great red carpet choice for a young starlet - demure yet still sexy, we love this look on Seyfried. Bonus points for the fab accessorising - the chunky necklace looks great and the (toned) bare legs and beige harness heels are just right.
We're not quite sure what happened here, since Sevigny is usually so spot-on with her quirky fashion choices. The slicked-back hair and red lips are way too much, and the bondage-style masculine-meets-feminine approach (oversized blazer and bowtie paired with garters?) doesn't work. And let's not even get started on the oversized jungle print shirt-dress...
The Alice in Wonderland and Jane Eyre star is still a relative newcomer on the red carpet, but this look is picture-perfect. The Elie Saab gown is stunning and still playful, and her slightly dishevelled updo complements the dress and her face.
Avril's still rocking the punk-princess look, which has its moments - unfortunately, this isn't one of them. Too much going on with all the different fabrics (sequins, satin, tulle), the stripy multicoloured hair, the combat boots and the jewellery.
