Sisley’s Christine d’Ornano on Carolyn Bessette-Kennedy, The River Café and London’s Pimlico Road

My personal style signifier is a necklace that is hung with the baptism medals of my three daughters and a coin with our family crest on the back. It sort of brings me luck.

The last thing I bought and loved was an original poster of Björn Borg commissioned by Roland Garros for the 1981 tennis tournament. I had liked it for years but was on a bus in Paris last year when I saw it in a gallery window and immediately jumped off and bought it. It reminds me of watching endless Borg versus McEnroe matches when I was small. From €300; Librairie Elbe, 213 Bis Boulevard Saint-Germain, 75007 Paris (+331-4548 7797; www.elbe.paris).

And the thing I’m eyeing next is a 1970s black and white print by Argentinian artist Julio Le Parc, called A Partir d’un Ciel de Van Gogh. It was inspired by Van Gogh’s paintings of swirling skies, though it also looks like sea waves to me. £3,147; www.artspace.com.

A recent “find” is a shop called The Hackney Draper that has great fabrics and accessories for the home. I discovered it on Instagram, though I am not generally that savvy on social media. I bought a Moroccan carpet and some vintage saris that I am going to turn into cushion covers. 25 Chatsworth Rd, London E5 (020-3583 8485; www.thehackneydraper.co.uk).

The last item of clothing I added to my wardrobe was a pink, stripy Emilia Wickstead dress that I spotted at her spring/summer 2016 show. The elegant and pretty pastel shade makes it stand out. Striped pleat-back Liv dress, £1,220; www.matchesfashion.com.

The books on my bedside table are IQ84 by Murakami, because the prose is as clear as water and I find it very relaxing; and, after the recent BBC television series, I am re-reading War and Peace. I read it when I was 14 and skipped the diplomatic scenes because they seemed boring, but I find them more relevant today.

The site that inspires me is Chapelle Notre-Dame du Haut in Ronchamp in France, designed by Le Corbusier. His inspiration for architecture was the human body and this really comes across in the curves of the building. 13 Rue de la Chapelle, Ronchamp 70250 (+333-8420 6513; www.collinenotredameduhaut.com).

The best gift I’ve received recently was a wonderful folklore-inspired blanket from Décors Barbares, embroidered with the words “Children’s Tales”, which came from a friend. There is something very Charleston Farmhouse and Bloomsbury set about it. www.decorsbarbares.com.

The best gifts I’ve given recently were brush pots From Pentreath & Hall for my close friends for Christmas, each decorated with the initial of their first name. 17 Rugby St, London WC1 (020‑7430 2526; www.pentreath-hall.com).

In my fridge you’ll always find cheese from La Cave à Fromage on Portobello Road; we are big cheese eaters and I buy a lot of really good English and French varieties there. We also always have Ladoucette Pouilly-Fumé white wine and Lindt Excellence 70% Cocoa dark chocolate, as well as the usual – butter, eggs and vegetables. La Cave à Fromage, 148-150 Portobello Rd, London W11 (020-7221 1000; www.la-cave.co.uk). Ladoucette Pouilly-Fumé, £30; www.majestic.co.uk.

An object I would never part with is the hand-stitched tapisserie clutch bag my mother made me with my three girls’ names on it; I use it when I go out for the evening.

The people I rely on for wellbeing are Annee de Mamiel for acupuncture for my face and body; there is something very special, almost mystical, about her. I come out feeling reconditioned and transformed. And my osteopath Amberin Fur – a few times I have had a really blocked-up back and she’s helped me out. Amberin Fur, 58 South Molton St, London W1 (020-7706 1997; www.osteopathuk.com). De Mamiel, www.demamiel.com.

The beauty staple I’m never without is our own Sisley Sisleÿa L’Intégral Anti-Age cream; it firms and plumps up my skin and makes it glow. £285; www.sisley-paris.com.

My favourite websites and apps are RitaKonig.com for beautiful presents, TheHoarde.com for vintage furniture and the Shazam.com app – a must as I am always trying to find new music.

My style icon is Carolyn Bessette-Kennedy. I knew her husband, John F Kennedy Jr, as we were related, but I never met Carolyn. She represents to me the essence of the Calvin Klein style of the 1990s and I find her look still relevant today.

The last meal that truly impressed me was lunch with my mother and cousins, who were over from Paris, at The River Café, a restaurant that continues to impress me. To start I had burrata with wood-roasted green vegetables and then pasta with crab and basil with a glass of Gavi di Gavi. Thames Wharf, Rainville Rd, London W6 (020-7386 4200; www.rivercafe.co.uk).

The last music I bought was Lana Del Ray’s Honeymoon; my girls love her music too and they play her songs on the guitar.

An unforgettable place I’ve travelled to in the past year is Sumba, a beautiful island in Indonesia where we went for two weeks last summer with about 20 family and friends. We all surf, even my kids, and surfers follow the wave; August is the best time for it. The people of the island are very special too, full of mischief and extremely elegant.

And the best souvenir I’ve brought home is a dozen very thin and fragile glasses from Venice with a red rim that I bought a couple of years ago on a whim. Good wine tastes even better in fine glasses.

If I didn’t live in London, the city I would live in is Paris for the museums, art galleries and flea markets; I also love visiting Astier de Villatte, a wonderful ceramics shop. Paris has my favourite places to eat, such as Le Petit Lutetia – a small, lovely bistro – and Anahi, an Argentinian restaurant in an old butcher’s shop, which is fun and very cool. Anahi, 49 Rue Volta (+331-4887 8824; www.anahi-restaurant.fr). Astier de Villatte, 173 Rue Saint-Honoré (+331-4260 7413; www.astierdevillatte.com). Le Petit Lutetia, 107 Rue de Sèvres (+331-4548 3353).

An indulgence I would never forgo is a bath, not only before I go to bed but also if I am going out, as a pick-me-up. I light candles and drop some lavender oil in the water.

My favourite room in my house is my living room. It has pink walls and a lush red velvet sofa that you can really cosy up on.

The one artist whose work I would collect if I could is David Hockney. He is the most fascinating artist, his work is so varied and he is such a great craftsman.

If I had to limit my shopping to one neighbourhood in one city, I’d choose Pimlico Road in London as I love passing by a few of my favourite interiors shops – Rose Uniacke, Howe and Soane Britain. I will have a look at Jamb for antiques and then have a coffee at Daylesford Organic. Daylesford Organic, 44B Pimlico Rd (020-7881 8060; www.daylesford.com). Howe, 93 Pimlico Rd (020-7730 7987; www.howelondon.com). Jamb, 95-97 Pimlico Rd (020-7730 2122; www.jamb.co.uk). Rose Uniacke, 76-84 Pimlico Rd (020-7730 7050; www.roseuniacke.com). Soane Britain, 50-52 Pimlico Rd (020-7730 6400; www.soane.co.uk).

If I weren’t doing what I do, I would be a furniture restorer – or something that involved seeking out old things and creating something functional out of them.
