Natalie Portman made a triumphant post-baby return to the Golden Globes red carpet in this fairytale pink gown by Lanvin with Tiffany & Co jewels.

She did a style 180 for the Oscars, though, opting for a more casual red polka dot dress (vintage Dior, darling). 

Angelina Jolie forced many to do a double-take when she arrived on the Golden Globes red carpet in something other than her signature black. Her cream Atelier Versace dress, accented with red and a severe, pulled back ‘do, earned her plenty of column inches.

But that was nothing compared to what thisdress, also by Atelier Versace, would do for her when she wore it to present an award at the Oscars. It made ‘Jolieing’ – sticking out a leg in a contorted pose – a phenomenon. 

It’s really been Kristen Wiig’s year, awards-wise, thanks to the success of her film Bridesmaids – although it didn’t take home any prizes at the Golden Globes. Showing off a darker ‘do, the actress was a winner in the style stakes though in this minimalist, slit-front dress by Bill Blass.

No, you’re not seeing double. Kristen opted for a strikingly similar – albeit a bit rufflier – dress for the Oscars. This one was J. Mendel. 

Life must feel like one long red carpet to Rooney Mara at the moment; the actress stepped straight off the Girl With The Dragon Tattoo promo trail and straight into awards season. Fortunately, she has a wealth of fabulous labels at her finger tips. Cue this dramatic, bustle-backed dress by Nina Ricci.

Talk about night and day! Come the Oscars, Rooney was in a far lighter, more romantic mood, and this Givenchy Haute Couture by Riccardo Tisci gown – plus full fringe – made the intended impact. 

Hollywood’s new girl crush, Emma Stone, played up her Titian locks in this burgundy degrade Lanvin dress at the Golden Globes. Red on red is the new black.

Sticking at her favourite spot on the colour spectrum, Emma opted for this fuchsia Balenciaga gown with a dramatic bow detail at the neck for the Oscars. 

With the spotlight on her thanks to her starring role in The Help, Jessica Chastain opted for a classic, high-necked cream gown – with little scope for wardrobe malfunctions, one imagines! – by Givenchy Haute Couture by Riccardo Tisci for her Golden Globes appearance. She even played it safe with her accessories, matching the pearl detail on her dress with pearl jewellery.

Fast forward to the Oscars, and what a change of direction! Gone is the high neck and fussy beading, and swept in is this opulent, embroidered, strapless creation by Alexander McQueen. 

Viola Davis, who also garnered her fair share of nominations with The Help, made a bold entrance on the Golden Globes red carpet in this Grecian-style Emilio Pucci dress replete with leg-flashing split. 

Despite keeping her fabulous pins under wraps at the Oscars, Viola still managed to make us turn green with envy thanks to this crystal-trimmed Vera Wang gown. (Note the co-ordinating emeralds: the work of a fashion pro.) 

Shailene Woodley is one of the hottest new names of 2012 and, thanks to her starring role opposite George Clooneyin The Descendants, she earned herself a spot on the most prestigious red carpets of the season. For the Golden Globes, she looked every inch the movie star in this soft, strapless Marchesa sheath paired with a chic up-do.

But playing is safe, apparently, isn’t in Shailene’s fashion DNA. The ingĂ©nue took a different tack altogether at the Oscars in this heavy and uber-directional cream dress by Valentino. 

Tina Fey often looks out of her comfort zone on the red carpet and her body language in this shot tells us that was the case at the Golden Globes, too. Though we’re frankly struggling to understand why; this beautiful plum Oscar De La Renta confection is one of her better dress choices.

Onwards and upwards! Looking much happier – and positively glowing – at the Oscars, Tina wowed in Carolina Herrera.

WINNER: Both dresses look great on this reluctant fashion plate, but it’s the Carolina Herrera that has the biggest wow factor as far as we’re concerned.

The Knowledge: how to be well dressed, by Kate Moss

The key pieces 
If you find a look that works for you, stick to it. I'm at my most comfortable in jeans and a blazer, and I'm not afraid of wearing different cuts of denim. I love skinny jeans but I'm feeling a flare at the moment - I'm really liking a wide leg. The pencil skirt is one of the most useful items to have in your wardrobe as it's always saucy (especially in black) and seems to work for almost everyone.
Look to the past 
Most women will have an era in fashion that they're drawn towards for inspiration. I really love the late 1960s and 1970s, around the time of the Rolling Stones. I don't channel it in everything I wear, but it does seem to feed through most outfits. The late part of the 1960s was an exciting time, with lots of changes in the fashion industry. It's important to have some inspiration or a reference point when you're dressing.

Work your style 
It's often only other people who notice you have a signature style. I don't think I've got one, though other people tell me I do. But it doesn't matter; even if you do tend to wear the same things all the time, it's how you wear them and your attitude that counts. Dressing is like modelling - you can constantly adapt and change.
Dress for your mood 
If you're going to an important dinner, you should plan what you're going to wear as you don't want to look silly. If I'm going to an event I make sure I plan ahead so that I don't have a fashion crisis. However, most of the time I dress depending on my mood. I just throw on whatever I feel like wearing at the time, which tends to come from the palette of black, grey or red. If I'm having an off day, I'll wear full black.
Be prepared to suffer 
I prefer to be comfortable and sometimes fancy wearing flat shoes, but there are definitely occasions where you've just got to go with heels. There are some comfortable heels that you can run around in, but sometimes it's more important to be well presented than to be comfortable.
The finishing touches 
It's important to accessorise and I always turn to the scarves, hats and sunglasses in my wardrobe. But wearing too many accessories at once can look very bad. I don't have any strict rules, but my husband does say not to wear a hat with glasses because I look as if I'm trying to wear a disguise. I always have a pair of Ray-Bans in my bag and lots of pairs at home because they seem to go missing. They're a real staple. And jewellery? I don't think you can ever have too much.
