Mummy's little punk princess! Harper Beckham rocks Dr Marten boots and purple jeans for day out with Victoria

Her mother Victoria might be one fifth of the biggest pop group of the last twenty years, but Harper Beckham had a distinctly grungy edge on Friday.

The youngest daughter of Posh Spice and David Beckham, Harper wore a pair of Dr Marten boots and purple jeans as her mother took her to Dover Street Market in Mayfair.

Sat in Victoria's arms, the little girl could grow up to be a punk princess yet.

On trend: Harper teamed her boots with purple jeans and a grey long-sleeved top as they went to Dover Street Market

Harper teamed her eye-catching bottoms with a long-sleeved grey top, and left her brunette hair loose as she enjoyed the day out with her mother.

Victoria, meanwhile, opted for a white roll-neck sleeveless jumper over a white T-shirt, teamed with black cropped trousers and sky-high heels.

She carried a black and taupe bag from her own collection and wore her hair scraped back into a ponytail, with aviator sunglasses.

Harper has boasted a very designer-heavy wardrobe since her birth back in 2011, but that's not surprising when her mother is a well-regarded fashion designer herself.

But with Victoria not yet releasing a children's line, she has been heavily relying on the pretty offerings from Chloe, with her daughter wearing numerous items from Clare Waight Keller's spring/summer 2013 over the last week.

And as well as her punky Dr Martens - a favourite of the skinheads of the '70s, youth subcultures of the '80s, grunge kids of the '90s and the hipsters of today -  Harper owns a cool pair of Classic Mickey Shoes from Vans x Disney Collection.

Though it seems not every wardrobe decision is made by her stylish mother, as Victoria recently revealed her little girl is already following in her footsteps, and comment on her mum's style choices before she leaves the house.

‘She definitely has a point of view,’ the fashion designer said before her spring/summer 2014 show at New York Fashion Week.

‘If I’m going out for the night I’ll come downstairs and she’ll say “oh nice dress mummy” or “nice handbag mummy.'

And the two-year old certainly seems to enjoy watching her mother's sartorial designs strut down the runways, sitting in her father's lap while the VB fashion show took place nearly every season since she was born.
