It seems even A list Hollywood actresses can't be bothered to keep up their perfectly groomed appearances all the time.

While Charlize Theron was the picture of glamour at a Christian Dior event last night, earlier this week she looked far more likely to turn heads for the wrong reasons.

In a flat cap, unflattering three quarter length leggings and an over-sized cardigan, she was unrecognisable from the glowing beauty who later graced the red carpet.

Clearly opting for comfort over style, she wore flip flops and attempted to disguise her unmade-up face in large sunglasses.

But later for the Dior event in Beijing, the Oscar winning actress pulled out all the stops to ensure she is still considered a style icon.

She wore a strapless, floor length gold dress, embroidered with sequins, with a matching gold clutch bag.

No longer hiding her hair under a hat, it had been perfectly styled with blonde curls framing her face.

The 33-year-old is well-known for dramatic transformations after she put on weight and shunned make-up to play a serial killer in the film Monster.

This week she was named as a a messenger of peace by United Nations Secretary General Ban Ki-Moon.
