Have you ever wanted to dress like Sienna Miller?

Better question: who hasn't?

Well, now you can. Even better than dressing like Sienna Miller, you can actually wear her clothes.  

The blonde beauty known as a fashion icon around the world is auctioning off her personal wardrobe for charity.

Miller, an actress and activist, has selected a various array of pieces from her wardrobe to auction on eBay through Nov. 17 and 100 percent of the proceeds will be donated to the International Medical Corps, which provides emergency relief and health care services to millions of people in 65 countries, according to FOX News.

As a vocal advocate of the International Medical Corps, Miller has tried to turn focus onto real world issues outside the Hollywood bubble.

I first heard about International Medical Corps about three years ago. I remember being in California and stumbling across this horrific statistic that burnt into my consciousness: one woman in the Congo is raped every eight minutes. It terrified me, Miller told FOX411's Pop Tarts.

It terrified me not only because it exposed this violent abhorrence, but also because it exposed how unaware I was about the world I lived in. I felt embarrassed and angry.

I was in that strange and frustrating place that I think we've all encountered when we learn about a great injustice and find ourselves suddenly impotent. You don't know what you can do about it. You don't know how to do anything about it. You don't have a weapon to fight it. International Medical Corps is that weapon.

Last week, the gorgeous Brit was honored at the International Medical Corps' 2011 Annual Awards Celebration in Beverly Hills with the Global Activist Awards.

Many consider her a diamond in the rough when it comes to charity. She is a rare-breed of Hollywood starlets who actually does a significant amount of charity work without having to constantly notify the press.

Miller has been a long-time spokesperson and Global Ambassador for the International Medical Corps organization.

Sienna has visited field programs in the Democratic Republic of Congo, Haiti and most recently, Ethiopia to raise awareness of the ongoing famine, said a source to FOX News.

She does a lot of work and does so without the need for it to be broadcast to the world or to inflate her own ego. It is actually something she genuinely cares about.

The fashionista has chosen dresses, jackets, jeans, boot, bags, heels, and hats to offer up to the public.

There is no minimum bid, so anyone can have a shot at scoring one of Sienna's coveted articles.
