My signature look is...

Francis Mallmann, chef

I have my cotton berets custom-made by my friend Romina Savastano in Argentina. They have my name embroidered on them and are fastened with a piece of brown leather. I probably have around 100, all in different colours. I often give them away to clients or friends. Everybody wants a beret!

Sophia Roe, chef and TV Host

I have hundreds of vintage T-shirts. They’re not all band T-shirts – I have one that’s a Japanese comic – but there’s a lot of character in them. Some of them are 50 or 60 years old and still in great condition. My most prized is probably my original Queen II T-shirt, which has a picture of Freddie Mercury looking beautiful and perfect. I love that album.

Penelope Tree, model

My fringe is quite a strong statement, but in some ways it was also something to hide behind. I also have this enormous forehead, so it kind of looks better with a fringe. There’s not much else I can do with my hair because it’s so intractable and fine.

Dua Lipa, pop star

My style depends on the day, because it depends on my mood. If you were to ask someone else, they would probably point out that you’ll always catch me wearing heels. I can wear them 12 hours a day and not even bat an eyelid. My feet can take anything – it’s my superpower!

John Derian, artist and designer 

I love my black Cutler and Gross glasses given to me by a friend who owns a shop called Map in Provincetown on Cape Cod. They’re sturdy; I’ve stepped on them, twisted one of the arms, and they’re still in great shape. I also wear antique French trousers in cotton and corduroy that I buy at the Marché aux Puces. They’re baggy, shapeless and comfortable. I like to get lost in my clothes.

Peter Blake, artist 

My personal style signifier is a three-piece black suit made by David Chambers, often in corduroy. And red braces, with a blue shirt. Quite early on in my career, I became friendly with Justin de Villeneuve, who was Twiggy’s manager at the time. He recommended that I get my shirts made at Turnbull & Asser, which I’ve done ever since. I may have looked like an old tramp, but I’ve been wearing Turnbull & Asser shirts, N Peal cashmere socks and braces from various places on Jermyn Street!

Lykke Li, pop star

I wear all white by day and all black at night. I’m quite simple: I like white socks, a white T-shirt, white trousers. And at night, I’m often in black vintage 1990s Prada: I particularly love my leather A-form trenchcoat, and some knee-high boots that I’ve worn to infinity and are falling apart. I’ve been travelling so many years that everything has to work, and last forever. Anything I buy, I like to think, “I’ll wear this when I’m 70 and I’ll be so chic.”

Mr Chow, restauranteur 

My moustache and my glasses. I grew a moustache when I was very young – they were popular then because of Clark Gable – and that was the beginning of what I call “trade dressing”. It’s a device for instant recognition. The greatest trade dresser of all time was Andy Warhol, with his ridiculous wig. I adapt a lot of Andy’s philosophy, but in my case it’s for practical reasons. As the racism at the time was so severe, I had to wear a mask to disguise my Chineseness in order to survive in the west. I couldn’t wear an actual mask, but the glasses became a trademark. They are by Cutler and Gross, made in two colours; they’re called Mr Chow glasses. Same as my [George] Cleverley shoes; they call them Mr Chow shoes.

Peggy Kuiper, artist

Yohji Yamamoto’s collections – especially menswear – are my go-to. When I paint, I like to wear something comfortable that I can stain without worrying about it. I’m an introvert by nature, so I’d rather blend in and be the observer when I’m in a crowd.

Harry Lambert, stylist

I have a few Éliou necklaces, and I wear one every day. The brand is based in Miami and run by Cristy [Mantilla] and Duda [Teixeira], and all the jewellery is made by hand. I began by wearing one with mixed pearls and colourful beads, and now I’m drawn to these large, Marge Simpson-esque necklaces. I feel naked when I’m not wearing them.

Cynthia Nixon, actress

I love bold silver jewellery – usually Native American, Indian or Moroccan – especially a collar necklace that I never take off. I sleep in it and it makes me feel armoured and powerful. I also always wear a single flower on a chain that I bought in New Mexico – it’s by James Faks, who is affiliated to the Blackfeet and Oneida Nations – and a star that was my Sex and the City character Miranda’s back in the day. They just make me feel great.

Liz Lambert, hotelier and designer 

I have a day-to-day uniform of T-shirts in indigo and black by Filth Mart and Velva Sheen, a pair of jeans, and custom-made “roper” boots by Ranch Road. They’re comfortable, sturdy and I love the backstory of the maker, Sarah Ford, a former Marine who did three tours in Iraq and Afghanistan before going to Harvard Business School and launching this very Texan brand. My friend Jenna Lyons has said to me that I dress equal parts west Texas rancher and Japanese man – that sums up my aesthetic perfectly.

Andrew Logan, sculptor, jeweller and performance artist 

I’ve worn colourful silk Nehru suits since I first visited India in 1982. My very first was made for me in the city of Vrindavan, near where Krishna came from. I always wear one of my big jewel brooches made from mirror and resin, and Bukharian kippah-style hats. To me, wearing a Nehru suit is like slipping on an elegant tracksuit. I have every colour save for black; I wear purple for funerals.
