Best &Amp; Worst Dressed Of The Week: 19 March

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.,feedConfig,localizationConfig,entry&id=992197&pid=992196&uts=1300473507

15 March: Katie Holmes in a top from The Row, Nina Ricci jacket and Lanvin skirt as she takes daughter Suri to Serendipity in New York

Our favourite look of the week belongs to Katie Holmes - not only is her ensemble feminine and lovely and suits her perfectly, we think it's one of the best outfits we've seen on the star. Love the delicate grey colour and that Lanvin skirt is so dreamy.

13 March: Tamsin Greig at the Olivier Awards in London

Is Greig auditioning for the latest instalment of Aladdin? This genie-inspired jumpsuit isn't a good look - on the red carpet or off - and the bold print just puts it way over the top.

15 March: Thandie Newton in Louis Vuitton at a LV party for Sam Taylor-Wood in London

We love how Thandie's styled this hard-to-pull off Louis Vuitton dress - the playful high bun and sweet accessories make this a winner. What a great cocktail party ensemble.

16 March: Nicole Scherzinger arrives at a TV interview in Paris

The Pussycat Doll has been teetering on the edge of a style mishap for some time now (what was the deal with her bevy of hats last week?), but this outfit, with the scrunchy thigh-high white leather boots and mini-dress, is definitely a fashion miss.

15 March: Selena Gomez in Emilio Pucci at the Late Show with David Letterman in New York

She may be getting death threats from lovelorn fans for her relationship with Justin Bieber but that hasn't stopped this teen queen from stepping out in style. There are lots of different fabrics and textures going on in this dress, but Gomez makes it look just right. We also like that it's sexy but not brazen.

15 March: Christina Aguilera at a press junket for NBC's new singing competition, The Voice, in L.A.

Considering this is Christina's first public appearance since her recent arrest, we were hoping for a little more glamour and a little less trashy. The satin dress looks cheap, as do the extensions and the accessories (um, why did she pair a casual black leather studded belt with a cocktail dress?) are another miss.
