See How Taylor Swift Changed on Red Carpet

"I'm 23. I feel like I'm allowed to wear something a little low-cut," said the star, who made good on her promise at the 2013 Grammys, wearing a navel-grazing J. Mendel gown.

Oscars Fashion: The Best Dresses from 2005 - 2013

Beyonce 2005
Beyonce's enviable, strong style has been creating girl crushes since long before her recent Super Bowl performance. And this glamour-filled Atelier Versace look, which she sported to the Oscars in 2005, is sophisticated while keeping the performer's signature edginess intact. We dig.

Michelle Williams 2006
Michelle Williams was a burst of chic, sophisticated sunshine in the pleated, mustard-hued Vera Wang number she wore to the 2006 awards. Her loose, romantic bun and bold red lips only added to the simply powerful look.

Cate Blanchett 2007
If fairy dust and a moon beam had a baby, we're convinced it would look like the magical graphite-hued Armani Prive gown that Cate Blanchett wore to the 2007 Oscars.

Marion Cotillard 2008
Marion Cotillard channeled a modern mermaid in the elaborately beaded Jean Paul Gaultier fishtail gown she wore while accepting best actress honors at the 2008 ceremony for La Vie en Rose. Both Edith Piaf and Princess Ariel would be proud.

Anne Hathaway 2009
Anne Hathaway looked like beacon of light in Armani Prive at the 2009 Oscars. Which is great, considering a mere two years later she, uh, bombed as the show's host. At least her magicdress.co.uk evening dresses were good then, too.

Zoe Saldana 2010
Zoe Saldana has compared the trippy Givenchy Couture gown she wore to the 2010 Oscars to an "Avatar dream." We'll just call it wildly creative and contemporarily elegant and leave it at that.

Sandra Bullock 2011
The red strapless Marchesa ball gown that Sandra Bullock wore to the 2011 Oscars is as elegant and movie star-ready as Oscar dresses come.

Gwyneth Paltrow 2012
GOOP did it again last year in a chic, simple, asymmetrical Tom Ford dress and matching cape.

Jennifer Lawrence 2013
THE 85TH ACADEMY AWARDS(r) - RED CARPET ARRIVALS - Oscars(r) for outstanding film achievements of 2012 are being presented on Oscar Sunday, February 24 , at the Dolby Theatre(tm) at Hollywood & Highland Center(r), live on the ABC Television Network.

Celebrities in One-Shoulder Dresses

Trends are ever changing and one that we have seen a lot of in the last few weeks is that of the one shoulder gown or dress. Hollywood fashion is a little crooked - and we wouldn't have it any other way! Worn in a multitude of colours and designs, we take look at celebrities who carried off this trend with ease.

Most of us can only dream of having the lean legs and perfectly-placed curves of Blake Lively, but if we did we're more than certain we'd be wearing this thigh-skimming corsage dress by Marchesa.

Sarah Jessica Parker didn't fail to take centre stage in yet another winning look at the ShoWest Gala, as she worked this season's vogue for stand-out brights in a canary-yellow Lanvin dress. She showed off her signature preened pins with a less formal thigh-skimming hemline, but upped the elegance with the statement ruffled shoulder.

Lisa Haydon: At the Chivas Kwan Bash, the dusky model/actress wore a one-shoulder Stella McCartney gown.

Gwen Stefani dazzled in gold at the Met Ball, wearing a piece from her own line, L.A.M.B. Layered tulle with a peekaboo black lining was a glamorous accent to the look, and her slicked-back hair helped to show off her nearly-bare shoulders.

A deep ochre gown by Jason Wu was Diane Kruger's choice for this year's SAG awards. One of the most stunning looks of the night, the asymmetric shoulder detail flattered her delicate shoulders a treat. Her bright red lip look and the glamorous train had her looking like an old school Hollywood beauty.
