Mary-Kate Olsen loves Gigi Hadid's "effortless" style.
The 28-year-old actress turned fashion designer - who co-founded label's The Row and Elizabeth and James with her twin sister Ashley - is impressed by the 19-year-old model's laid back style while Ashley is a fan of Amber Heard's "bohemian look".
When asked to name their style pin ups, Mary-Kate said: "Gigi Hadid - whether she's on the carpet or the street, she always looks effortless and cool."
Ashley added: "Amber Heard - she balances her bohemian look with a touch of edge."
The siblings - who have worked together since they starred in the television series 'Full House' in 1987 - also shared the secret to maintaining a successful working relationship.
Mary-Kate explained: "We've always worked together so it feels natural to us. To be able to have a sounding board and to trust the person who is your partner, is beneficial across all aspects of running a business."
Ashley added: "Listen to each other's ideas and opinions. It exposes you to other perspectives."
The stylish pair were also happy to share their wardrobe staples and Ashley revealed her look is all about being comfortable.
She told Miss Vogue: "Silk blouses, denim, loafers, scarves and a bag that can fit all my things. Comfort is important."
While Mary-Kate chose her favourite pieces from their lines.
She said: "Old Textile Elizabeth and James denim, The Row Button Down, my vintage jewellery, sunglasses and a pair of classic pumps."
