Kate Winslet appeared on the red carpet earlier this week for the premiere of her TV mini-series Mildred Pierce as part of the Venice Film Festival. For the occasion Kate showed off not only her impeccable sense of style but also that she knows how to dress herself to perfectly compliment her shape. Kate wore a body-contouring colour-block dress from the fall collection by Stella McCartney teamed with Yves Saint Laurent black peep-toe heels.

Anna Paquin made an appearance on the panel discussion for HBO’s True Blood press tour in Beverly Hills last week. Anna who is sporting a far more glamorous long blonde tousselled hair do looked chic in a white polka dot sheer dress from the fall collection by Stella McCartney. On the runway the top of this dress is completely sheer but Anna opted for a classier look- covering up, for much more occasion appropriate attire. She teamed the dress with Yves Saint Laurent nude sandals.

Rosie Huntington-Whiteley appeared at last night’s Glamour Women of The Year Awards. The Transformers actress flew the flag for British designers choosing to wear a nude silk halterneck dress from the spring collection by Stella McCartney. I absolutely love this look; the dress design is the perfect mix of sexy – with its thigh split whilst retaining a pretty vintage feel, and of course it is worn beautifully by Rosie.

It was all going so well for Gwen Stefani at Cannes; first that edgy Stella McCartney jumpsuit, then the sequinned gown by her own label and now a rather bizarre white and black cutaway detail design by Armani Prive. I want to like this look after all Gwen has got the hair and makeup exactly right but her chosen gown does nothing for her with the cutaway detail making it a little more cheap – which couture definitely isn’t.

Gwen Stefani and Gavin Rossdale attended the Cannes Film Festival yesterday for the premiere of Brad Pitt’s new movie; The Tree of Life. The married couple made quite the rock star couple on the glam red carpet. Gwen opted for a black sequinned plunging neckline jumpsuit by Stella McCartney, a great alternative to a gown on the red carpet.

Penelope Cruz continued the worldwide promotional tour for the new Pirates of the Caribbean movie; on Thursday she appeared in Westfield for the London premiere. For the event Penelope chose a white lace Givenchy haute couture design from last year’s fall collection. It’s hard to find fault with Riccardo Tisci’s designs for Givenchy but this dress doesn’t fit Penelope particularly well, a design from the most recent couture collection may have been a better option.

The next stop for Penelope and Johnny Depp was the Cannes Film Festival where they appeared today for a photocall. This time Penelope chose a much more flattering look; navy and velvet halterneck dress from the new fall collection by Stella McCartney, Casadei pointy stiletto heels finish off the much sexier look. The outfit that really grabs my attention here however is that of newcomer Astrid Berges-Frisbey. Astrid wears the chicest little ivory dress look from the spring 2009 haute couture collection by Chanel.

Reese Witherspoon and her co-star Robert Pattinson brought a dose of Hollywood to London’s Westfield shopping centre last night for the premiere of their new movie, Water For Elephants. Reese showed her support for British designers wearing a blue off the shoulder dress by Stella McCartney. She teamed the pretty dress with nude Christian Louboutin pumps.

It may have an evening celebrating the opening of an Alexander McQueen exhibition but Stella McCartney faired rather well on the red carpet, dressing an impressive list of attendees. First up Kate Hudson, the pregnant actress chose a strapless metallic gown for the event by Stella McCartney. The dress with it’s embroidered top was a pretty choice and makes an ideal cut on her fast growing baby bump.

Rihanna, the racy popstar chose an equally racy dress. She went for a lace design custom made by Stella McCartney. The dress features an open panel running all the way up the side of the dress. The look is a not unexpected dose of red carpet drama although a more traditional look might have been a nice unexpected twist to her usual style shock tactics.

Madonna made a rare appearance at last night’s gala. Madonna doesn’t always get it right but on this occasion the cap-sleeved silk blue gown was a perfect choice. It’s elegant, flattering and age appropriate!

Eva Mendes can normally be relied upon to bring a big dose of old Hollywood glamour to the red carpet. On this occasion she went for an alternative look; instead of the traditional va va voom we’re used to she went for a more trend led 70s inspired blue pleated gown with metallic waist-belt from spring/summer by Stella McCartney.

Gwyneth Paltrow can usually be relied upon to wear a fabulous gown by her friend Stella McCartney, she didn’t disappoint. Last night choosing a metallic floor-length gown by the designer. The dress is actually very simple and faff-free, the high neck and long-sleeves give it a very chic appearance but the thigh split means it isn’t without a side of sexiness!

Actress Maggie Gyllenhaal attended the event in a stunning midnight blue sequinned gown, custom made by Stella McCartney.

Finally young actress Hailee Steinfeld has not only been making waves in Hollywood with her Oscar nomination but also in the fashion world. She continued rising in style stakes with her appearance at the Met Gala last night in a high-necked embroidered gown from the pre-fall collection by Stella McCartney. I like that Hailee hasn’t tried to dress older than her age by going for a full length gown, keeping it short maintains a fresh, youthful vibe.

Alexis Bledel has been on a fashion fest for the last week. The Gilmore Girls star is busy promoting her new movie directed by Robert Redford, The Conspirator. On Sunday she appeared at the Washington premiere in a simple longsleeved dress from the pre-fall collection by Stella McCartney. A pair of gold Alejandro Inglemo sandals dress up the look.

On Monday Alexis appeared in New York for the red carpet premiere. For this occasion she went for a dressier look in an embroidered cap-sleeved gown from the pre-fall collection by Oscar De La Renta. The dress (as with most ODLR designs) is exquisite and the addition of black Giuseppe Zanotti sandals are the perfect accessories.

Last night Hollywood stars gathered in Santa Monica for the 2011 Independent Spirit Awards. The awards ceremony is the premier event in the Independent Film Makers calender. The lady of the night was of course Natalie Portman who took away best actress for her role in Black Swan. Despite the fact that pregnant Natalie has a rapidly expanding waistline to deal with she still manages to look stylish.

Last night she wore a pretty yellow and beige dress from the new spring collection by Givenchy teamed with nude Stella McCartney pumps and a yellow Givenchy clutch. Who will dress Natalie for the big night tonight is becoming a rather puzzling riddle with Natalie really mixing up her choice of designers in the past month.

Zoe Saldana attended the ceremony, showing off a fab pair of legs in a leopard and lace mini dress from the new spring collection by Dolce & Gabbana. The outfit is set off perfectly with a pop of colour from Zoe’s coral orange Brian Atwood pumps.

Eva Mendes looked summery in a multicolour printed dress from the spring collection by Chanel, paired with mint green Pierre Hardy sandals. Eva hasn’t been about on the red carpet for a little while but when she does make an appearance, like last night, always manages to look fab.

Next up is best actress nominee Nicole Kidman. Nicole wore one of her favourite designers, L’Wren Scott. She looked chic in a fitted red lace dress, the hemline and neckline of this design is great on Nicole being both stylish and age appropriate. A pair of Charlotte Olympia shoes adds a quirky finish to the look.

Finally actress Naomi Watts arrived alongside her other half Liev Schreiber. For the event Naomi went for a chic look by Chanel; black halterneck detail knit dress and cropped tweed jacket from the spring collection and a resort multi-colour patchwork print bag.

I’ll be blogging red carpet looks from the Academy Awards live tonight so check back for the lowdown on who wore what!
