What do Kirsten Dunst, Penelope Cruz, Uma Thurman have in common? No, it’s not the fact they are three beautiful actresses. It’s the fact that when you put them on the red carpet, they do nothing but shine. At Cannes Film Festival, people may remember the winner of the coveted Palme d’Or, but they’ll also remember the dresses that sparkled, the flawless faces and the figure-hugging numbers that played with the imagination. Here are my highlights from this year’s full-filled festival on the French Riviera:

Calvin Klein La Croisette beach party
Joanne Black style: Myla dress, YSL heels and Sergio Rossi clutch
Calvin Klein parties are a magnet for beautiful women – which makes them ideal for a bit of style spotting. There were a number of contenders for the best-dressed crown. Standing out from the star-studded crowd were both actress Vanessa Hudgens, who wore a flashy yellow Calvin Klein dress, and Jessica Chastain, whose on-trend orangey red number with red sandals and a white clutch caught more than a few eyes. Close behind were top model Laura Stone in a gold figure-hugging dress, which she matched with some beach-friendly flats, Clemence Poesy sporting a 60’s-style white mini shift dress and festival judge Uma Thurman in an embellished black dress.

Duran Duran – Belvedere party @ VIP
Joanne Black style: Jitrois leather dress, Alaia belt, YSL shoes and a Chanel bag
Those who go to see Duran Duran in anything other than a rock chic style do so at their peril. This legendary British band is just made to be followed by leather-clad fans in sexy black numbers. With access to the VIP area back stage, I was well-placed to catch all the fashion action. For a second time, Vanessa Hudgens led the way in a stunning black dress and leather jacket – teamed I’d like to add with the same YSL heels I wore! Jamie Foxx also looked cool dressed all in black – perfect for his turn behind the microphone – and jury judge Jude Law was his stylish self in a grey blazer and white T-shirt.

Charles Finch’s 3rd Annual Filmmakers Dinner @ Hotel du Cap Eden Roc
Joanne Black style: YSL jumpsuit and shoes
Find yourself with an invite to one of Charles Finch’s prestigious soirées and you know you’ve arrived. For his guest list is like no other. Setting the style standard, Charles himself was looking as good as ever in a blue shirt and espadrilles from his new brand Chucs. Add Jane Fonda – who wore a dazzling floor-length off-the-shoulder black gown – Mick Jagger and his fantastic designer girlfriend L’Wren Scott (who looked elegant in her own design) and legendary music producer Richard Perry into the mix and it’s not hard to see why the Filmmakers Dinner is still the hottest ticket in town. It was great to see top new couple Emily Browning and Max Irons getting cosy and I also have to mention Tods’ CEO Diego Della, who showed us how the smart/casual look should really be pulled off – wearing a black and white scarf as a tie, with a black shirt (collar standing up), a navy blazer and jeans.

De Grisogono Dinner
& After Party @ Hotel du Cap Eden Roc

Joanne Black style: Roberto Cavalli gown and de Grisogono diamond Earrings
Fawaz Gruosi, founder of de Grisogono, is a man who understands beauty. He also understands that when you mix dinner with diamonds, dancing and daring dresses, your parties become a mecca for sparkling fashionistas. This party was less about the clothes and more about admiring the bodies being shown off by them. Supermodel Bianca Balti, who arrived with Fawaz, has such a stunning waistline, it was nice to see it in a fringed white dress with a cut out waist. Karolina Kurkova also opted for the cut out style, revealing a little flesh with her dark chocolate brown dress. But the beautiful bodies didn’t stop there. With Goldie Hawn (in a beige floor-length silk fish skin effect Alberto Feretti dress), Ex Vogue editor Carine Roitfield in a sexy lace number, Naomi Campbell in full-length gown and Georgina Chapman in a short white piece of her own collection, there were plenty of well-toned and well-heeled wonders to observe. Designer Eva Cavalli also deserves a mention for leaving her dress at home, throwing out tradition and sporting a stylish black tux.

AmfAR Cinema Against AIDS L’Oreal Party @ Hotel du Cap Eden Rock

Joanne Black Style: Lanvin gown
Another party at Eden Roc, another opportunity for Goldie Hawn to show us just what it takes to be a leading lady in the style stakes. Wearing a soft pink Roberto Cavalli one-shoulder gown with diamante round the waist, de Grisogono earrings and a gold Shamballa bracelet, she took centre stage at this stunning event, designed to raise money for AIDS research. Of course, hers wasn’t the only stand-out performance. Also opting for a pale gown with diamante detailing was – the now Princess of Monaco – Charlene Wittstock. Supermodel Karolina Kurkova made an entrance in a short halterneck white Chanel number with gold chains, Gwen Stefani stepped out in a glitzy black halterneck gown with a fish tail and gold belt and L’Oreal model Doutzen Kroes took a turn in an orange mini dress with gold heels, a gold cuff and a blue clutch. And, not to be outdone, the men also gave us something to pour over – actor Sean Penn worked the all-in-black look (complete with skinny tie) and Renzo Rosso sported a trendy tux with a T-shirt and chain.

From the red carpet to pre-awards parties, Oscars week is all about style. In the ‘City of Angels’, you’ve got to be well-dressed if you want to impress – and get invites to all the right parties.

There’s nothing like a week of glamorous events to give your wardrobe a workout. Here’s what I packed for my stay at the Beverley Hills Hotel:

Balmain dress: I wore this with Sergio Rossi heels at the Soho House Grey Goose party. It was a real crowd pleaser – and conversation starter with a few celebs – and made a great addition to the suitcase.
Lanvin jumpsuit: This number kept me warm when it started to rain on the way to the Kevin Spacey Foundation event. With my Christian Louboutin heels and YSL accessories, I was all dressed up and ready to talk to the man himself.
Jitrois leather dress: Faced with a room full of leading ladies at the Charles Finch and Chanel party, I knew I had to pull out all the stops. Wolford tights, my Louboutin heels, Stephen Webster earrings and a hint of Chanel helped me complete the look.
Lanvin gown: No trip to Elton John’s viewing party would be complete without a fabulous gown, which I wore with my Prada fur, Chopard diamonds, YSL heels and a Sergio Rossi clutch.
Extras: I even found time to add a few new accessories, popping into vintage shop Decades for some fab earrings and the Chanel boutique on Rodeo Drive for a pair of stunning gloves – with that famous chain detail.
Chucs bikini: a must for all those morning after pool sessions.

With nights spent living out my A-list fantasies and days spent relaxing poolside, there were more than a few highlights from this week with the stars. To celebrate, here are my Style Academy Awards:

Best dressed man: Ok, so I’ve narrowed it down to a shortlist. First up is Jon Hamm who looks great even when he’s not playing Don Draper! I liked his beige suit and jade green shirt look when I caught up with him at the Grey Goose party. He said he’d just been at an Irish party and had discovered the expressed ‘cead mile failte’, which means a hundred thousand welcomes. Also worth a mention is Piers Morgan (looking sharp in a black suit, white shirt and blue tie) and Gerard Butler, who looked every inch the movie star in a grey suit, white unbuttoned shirt and black cashmere coat at the Weinstein pre-Oscars party.

Best dressed woman: It’s another list! Olivia Cole looked cool in a Temperley number with a Paul & Joe blazer at Soho House and Jennifer Lopez and Cameron Diaz showed everyone what a great personal trainer can do – Lopez was sporting a LBD that complemented her shapely pins and Diaz gave us all a treat by stepping into a mini dress. I also think Hayden Panettiere dazzled at Elton’s party in a long white gown with built in gold top.
Best celebrity spot: Too many to mention really, but highlights include having lunch sitting on the table next to designer Valentino and spotting Leonardo DiCaprio (hiding under a baseball cap), Serena Williams (wearing a short grey leather jacket over a tennis-style mini dress) and Helen Mirren (in a fitted top and yellow skirt) at Soho House.
Best use of sparkle: And the winner is… Heidi Klum. In glittery shoes and a Julien Macdonald gown, she sparkled on that red carpet.
Best red carpet look: Scarlett Johansson and Penelope Cruz deserve the title in this category. Both leading ladies opted for colourful, figure-hugging numbers that accentuated their stunning body shapes. Johansson wore a backless purple lace Dolce & Gabbana  dress and Cruz stepped out in true star style in a red sequinned L’Wren Scott dress, which she accessorised with Jimmy Choo and Chopard jewels.
Best use of Chanel (at the Chanel party): With a room full of ladies dressed in Chanel – everyone from Cate Blanchett to Uma Thurman – it was hard to pick a winner. I have to single out Naomi Watts though for her short cream skirt, see through top and soft pink bolero-style jacket, which she paired with cool ankle boots.
Best celeb chat: It’s got to be Kevin Spacey! We talked about his recent trip to Dublin and all the hot spots he visited.
Best sexy number: Sharon Stone kept it simple in a black Dior dress and really let her stunning looks do the talking.

Phew! After all that style, I need a rest.

Where: VIP Room
Joanne Black Style: Nude Martin Margiela dress, Sharon Wauchob jacket, Bottega Venetta earrings, YSL clutch and Sergio Rossi shoes

What’s better than spending the evening sipping wine at a lavish star-studded party? Sipping wine at two lavish star-studded parties! When faced with Charles Finch spectacular and Chopard’s 150th anniversary party, there really is only one option – go to both.

Fashionistas and film festivals are a match made in heaven, and you only need look round the room at a Chopard party to find out why. Less was certainly more at this event. While Paris Hilton went long with a beautiful plunging royal blue gown, Eva Herzigova wore a super-short nude number, presenter for the evening Myleene Klass went strapless with a knee-length nude outfit and Lindsay Lohen wore a short snappy number with silver-coloured shoulder accessories. Marion Cotillard even opted for an edgy alternative to the full-length gown, stepping out in a glitzy jump suit.

This was, however, a night dedicated to more than just the well-styled and the stylish. Lionel Richie gave a show-stopping performance, belting out numbers such as a Dancing on the ceiling and Easy on a Sunday Morning, and Jesus Luz did a great turn as DJ, helping us dance the night away.

Where: Hotel du Cap
Joanne Black Style: Nude Martin Margiela dress, Sharon Wauchob jacket, Bottega Veneta earrings, YSL clutch and Sergio Rossi shoes

Everyone wants an invite to a Finch Quarterly dinner. After last year’s exclusive event, which saw everyone from Mick Jagger and Ralph Fiennes to Rachel Weisz revel in the delights of a Finch feast, I expected to be surrounded by a who’s who of stars from the world of movies, fashion and the media. And I was not disappointed.

This, the second dinner of its kind, was hosted by the man described as the ‘Cannes-do guy’ in honour of Director Bertrand Tavernier. With a guest list that included L’Wren Scott and Christian Louboutin, I knew talk of fashion would be high of the evening’s agenda. L’Wren Scott wore a fab hot pink dress from her collection, which she teamed with some very interesting pink, yellow and green sandals, and Louboutin looked like he was having great fun talking to Sydney Ingle-Finch while sporting a bright blue hat with a yellow band. And I’m not surprised – the dancers for the evening were all wearing shoes from his collection.

But they weren’t the only ones making a style statement. Glenn Close looked elegant in an icy grey jacket and camisole, Jenson Button was every inch the champion of speed in smart jacket with a crisp white open necked shirt, Mick Jagger had a beautiful bold scarf and Dominic Cooper worked the black suit and skinny tie look to perfection.

If that wasn’t enough excitement for one night, I even got the chance to share a laugh with ex bond villain Mads Mikkelsen, who played Le Chiffre in Casino Royale, before rushing off to another party with friend Mira Anafina.

Where: The Palm Restaurant, London
Joanne Black Style: Sharon Wauchob blouse and jacket, Jitrois leather leggings worn with knee high Lazar cut-over-the-knee boots

Having lived in New York for 3 years, I find it hard now to get through November without Thanksgiving. So, when invited to a London lunch hosted by Arnaud and Carla Bamberger and Charles and Sydney Finch, I jumped at the chance to join the celebrations.

The Bambergers and the Finches certainly know how to attract a stylish crowd. Elettra Rossellini – the face of Lancome – wore a fab pair of green tights with a short LBD showing of her long legs, models Astrid Munoz looked great in a mustard top (the perfect colour for her skin tone), while English rose Saffron Aldridge kept it simple and stunning in a white shirt. Hostess Sydney stole the show, however, with an elegant grey textured wool Prada dress.

Given I will be basking on a beach in the sun when most people are tucking into Christmas lunch this year, a three course lunch with turkey and all the trimmings was a welcome sight. Whoever said beautiful people don’t eat, though, obviously hasn’t been to a Thanksgiving event. I have never seen pecan pie disappear so fast and plates look so spotless!
