So you wouldn't be wrong in assuming that Pixie Geldof knew a thing of two about fashion.
But the socialite and model, who turned 21 on Saturday, suffered a severe wardrobe malfunction at the Topshop London Fashion Week show.
Fashion faux pas: Pixie Geldof's denim dress does little to flatter her and she seems to have died her peroxide locks herself over the sink in her bathroom
Dressed in a shapeless denim dress, Pixie looked ready for a sunny Sunday drinking cider by the Lock in Camden.
Pixie's locks were also bundled in a scruffy bun, with messy roots poking through, suggesting she had done a DIY peroxide job over the sink in her bathroom.
Style mish-mash: Pixie sports scruffy hair and a neck tattoo, together with pearl earrings
The unkempt tresses and neck tattoo were juxtaposed with pearl drop earrings that appeared to be quite expensive.
But despite the shambolic look, Pixie has earned herself a reputable position in the fashion world.
Sir Bob's daughter has been the face of advertising campaigns for Levi's, Diesel, Agent Provocateur, Loewe and Pringle of Scotland.
She has also modelled for high street brand Debenhams and has walked in shows for PPQ, Luella and Jeremy Scott.
Nevertheless, her efforts at the House of Holland show on Saturday were equally as disastrous as she stepped out in a garish orange outfit.
Resembling a fortune teller, barring a crystal ball, Peaches' sister wore giant gold hoop earrings and a floor-length skirt decorated with bones.

Disastrous: Pixie with Eliza Dolittle, right, who didn't do much better, wearing a skirt with a hemline resembling a Dalmatian
