The 20-year-old singer - who has her own range of clothing for UK high street chain Lipsy - admits the 60s American actress has always been an icon of hers while fellow popstar Katy shares a similar taste in clothes.
She told more! magazine: "I'm a big fan of the 60s - Edie Sedwick is my style icon. I love it when this season changes and you can bust out the chunky knits and layering.
"Katy wears some really cool, young things. And she's obsessed with cats
too, like me. I love anything cat-related, so I'll be living in the leopard-print hot pants from my Lipsy range."
As well as talking about her own icons, Pixie also gave some advice on dressing to feel confident and look good.
She said: "Wear what you're comfortable in, it's as simple as that. Don't be dictated by trends, wear what suits you. There are definitely things I
wouldn't wear which I don't feel comfortable in.
"I love dresses with waist-belts, as they nip you in at your smallest part and skater skirts are great for skimming over your thighs."
