From way back in 2003 Sienna Miller has been on our fashion radar. Take a look through some of her best and worst outfits of all time.

Sienna Miller is one celebrity whose style has evolved quite considerably over the years. Read on for everything about Sienna Miller's style.

Since finding fame back in 2003, the pretty actress has tried out a number of different looks. As we chart her fashion transformation, it'll become quite clear that Sienna has never been afraid to experiment with the latest looks and trends. Perhaps this explains why she's become a real style icon during her time in the spotlight.

Although she likes to update her look season after season, there's one theme that's recurring. Sienna finds boho pieces impossible to resist.

Whether she's at a muddy music festival, out running errands in New York or posing on the red carpet in LA, the slender A-lister knows floaty garments are something that she can totally pull off. She loves to complement her laid-back ensembles with fuss-free hairstyles such as halo braids and flowing, tousled waves. No discussion of Sienna's love of haute hippie styling would be complete without a mention of the beautiful full-length Gucci gown she donned for the Cannes Film Festival Closing Ceremony in 2015.

Sienna - who's starred in films including Alfie, Layer Cake and American Sniper - teamed her simple white top with a beautiful Stella McCartney skirt to step out in NYC. We're sure it's a look she'll recycle time and time again in the future - and we don't blame her.

Sienna loves to mix up hemlines - we've seen her in everything from thigh-skimming short minis to glamorous gowns featuring a long train. She's also been snapped wearing frocks with an asymmetric cut at glitzy events on a number of occasions.

Judging by the ensembles she picks, Sienna looks to have many top designers on speed dial. Sienna - who welcomed her first child with partner Tom Sturridge back in 2012 - regularly wears pieces by Chanel, Valentino and Dior.

If there was one trend ruling the red carpet at the 2009 MTV Movie Awards, then it had to be thigh-skimming minidresses. Leading the pack was our very own Sienna Miller. Wearing a jade green glittering minidress from her Twenty8Twelve collection, the Brit actress reminded us all of her style icon status, and looked radiant with her signature blonde locks tumbling and a pair of vertiginous metallic heels elongating her picture-perfect pins.
