Best Dressed: Fool's Fete @ The Mandarin Oriental, NYC

Last Wednesday night, a flurry of glamourous Manhattanites descended to the ballroom of the Mandarin Oriental, New York for the Fool's Fete, the annual gala held in aid of New Yorker's for Children.  

Without a doubt, the award for best dressed went to Diane Kruger, who stunned fellow guests in a pink feathered dress by design duo Marchesa. 

Hilary Rhoda looked effortlessly chic in a canary yellow cocktail dress by New York designer, Rachel Roy. 

Rachel Zoe, showed off her trademark style in a glamorous navy gown.

And doing it for for the Brits...Poppy Delevigne, in a dazzling white gold number.

Label Lust: Halston

Halston, Bianca Jagger and Liza Minelli in Studio 54.

Roy Halston Fenwick, the iconic seventies designer was famed for his draped jersey dresses and ultra suede wrap coats coveted by Jackie O, Bianca Jagger, Elizabeth Taylor, Liza Minelli and a host of other A-list clientele. 

His designs. laid-back, yet decadent, earned him a wealth of praise - with Newsweek dubbing him 'The premiere fashion designer of all America'.

After studying in Chicago, Halston moved to New York City, where he became Head Milliner at the American department store, Bergdorf Goodman. It was here that he designed the famous Pillbox hat for Jacqueline Kennedy. She wore the hat during JFK's inauguration and, all of a sudden, Halston was a household name. 

But it wasn't until the 1970's, with the launch of his eponymous women's ready to wear line, that the brand truly took off. Halston  became the toast of New York society and a regular at the famed nightspot, Studio 54. 

His name became synonymous with the excesses of the lifestyle he afforded. His drug use spiraled out of control and was met with a failure to meet deadlines. In 1984 he was sacked from his own company and refused the rights to design and sell clothes under his own name. In 1990, at the age of 57, he died from an aids-related causes. 

On the red carpet: Vintage Halston

The brand was revived in September 2008 by Harvey Weinstein, Jimmy Choo's Tamara Mellon and stylist-to-the-stars, Rachel Zoe. 

Halston TODAY: Fashion Week, 2008

Former Versace Designer, Marco Zanini was named as Creative Chief. Although, despite the success of the first collection, there were rumours of disagreement on the creative board and Zanini was dismissed in July 2008. 

With no successor being named, the Spring 2009 collection was created by an unnamed design team. 

Despite the brand's worrying lack of direction, the collection didn't fail to impress. Minimalist creations in cascading jersey and billowing chiffon ensured lusty gazes on the faces of fashionista's everywhere...

Long Wrap Dress, £1, 755 

Clou Boots, £995

Silk Jersey Scarf Dress, £935

Hanna Suede Bag, £1, 095

In case we were in any doubt, Dasha Zhukova, last week, established her reputation as one of the most stylish women around at the opening party for David Lynch and Christian Louboutin's Fetish Photography show in Moscow. Roman Abramovich's other half proved that Rodarte can be worn off the red carpet, dressing down her pink and white creation with a black leather tuxedo jacket and metallic heels.

The cocktail dress is from Rodarte's Ready to Wear Spring 2009 collection. Here are my favourite picks from the label's show at fashion week...

Celebrity Hair Trend: Bohemian Rhapsody

This season's hottest hair trend has to be the headpiece. And what's so great about it is it's versatility: from Erin Wasson's feathered headdress to Nicole Richie's Eastern-inspired band. 

At a time when most of us are having to curb those pricey trips to the hairdressers, hair accessories are a fabulous way of experimenting and creating thrifty new looks.

On the high street

Urban Outfitters (www.urbanoutfitters.co.uk ) have a fabulous collection of headpieces: you'll find feathered clips, bohemian scarves and plaited headbands. Here are 3 of my favourites:

 

And the best of the rest

Short Feather Headband, £25, Topshop  

Shelly Embellished Bando, £12, Accessorize 

Large Flower Cream Bando, £10, Accessorize 

As it's spring, I'm planning on treating myself to a floral number. At her Fashion Week show, Diane Von Furstenberg pioneered the look with models dressed in colourful floral bands...

I have my eye on this Flower Cluster Band from Topshop...At £10, it's a cheap and chic take on DVF's catwalk look.

Best Dressed: Taylor Momsen @ Topshop Launch Dinner NYC

When most of us were 15 we were working bootcut jeans and tacky tees and had homemade highlights from a bottle of sun-in...But not Taylor Momsen. The Gossip Girl star is fast making a name for herself as one of America's most fashionable up-and-coming stars. This outfit, which she wore to the Topshop Launch Dinner in New York, perfectly showcases her rock chic style. I would have loved to see her with nude lippie, not pink and maybe a beaded clutch to soften the look. But maybe I'm just suffering from boot envy...those Emma Cook for Topshop brother creepers look fab on her.
