My personal style signifier is a pocket square. It takes a lot of thought to match one with a tie and suit; the balance has to be right. For work I tend to wear Charvet, which I have collected for 15 years; at weekends, with a blazer, I choose Hermès, of which I have more than 30. From £50; www.charvet.com. From £110; www.hermes.com.
The last thing I bought and loved was a pair of handmade Tucci riding boots. It usually takes a while to break them in, but Tucci uses very soft leather, plus they are elasticised and have a zip at the back for comfort. From about £649; Vicolo Barriera 2, 31058 Susegana, Italy (+3904-3843 5510; www.francotucci.com).
And the thing I’m eyeing next is a Porsche 911 Targa 4S. Porsche respects the classic cabriolet design but pushes boundaries with state-of-the-art technology. From £96,413; www.porsche.com.
The best souvenir I’ve brought home is powdered green matcha tea from the Nezu Museum café in Tokyo. I discovered it during a tea ceremony at the museum and buy it every time I visit Japan. It is excellent quality and I drink it throughout the week. 6-5-1 Minamiaoyama, Minato, 107-0062 Tokyo (+813-3400 2536; www.nezu-muse.or.jp).
The last music I downloaded was Handel’s Rinaldo and a compilation of his arias and duets called Love Handel by the conductor Laurence Cummings and soprano Ana-Maria Rincon. I appreciate the simplicity of Handel’s melodies; they immediately draw you in.
The best gift I’ve given recently was a Smythson jewellery roll, for someone who goes away a lot at weekends. I like how Smythson has repositioned itself as a brand and I own a lot of its small leather goods. Smythson jewellery roll,£170; www.smythson.com.
And the best one I’ve received was a pair of Anish Kapoor Water cufflinks from the Louisa Guinness Gallery, which specialises in jewellery designed by artists. They are circular and concave, and I wear them a lot. £7,200; 45 Conduit Street, London W1 (020-7494 4664; www.louisaguinnessgallery.com).
A recent “find” is The Upper House hotel in Hong Kong. Architect André Fu has followed typical feng shui principles, but there’s nothing old-fashioned about it. The interior is remarkably light – you feel as if you’re outside but actually you’re in a Hong Kong high-rise. Pacific Place 88, Queensway, Hong Kong (+852-2918 1838; www.upperhouse.com).
The person I rely on for personal grooming is my hairdresser at Josh Wood Colour, where I get the most amazing haircuts. It is tucked away in a tiny west London mews and you need to ring a bell to get in. They also analyse your hair and give you dietary advice based on the results. 6 Lansdowne Mews, London W11 (020-3393 0977; www.joshwoodcolour.com).
The last meal that truly impressed me was at Roka in Fitzrovia. The modern Japanese fusion food blew me away and there was the most amazing selection of shochu. It is flavoured so delicately and I tried several different varieties. 37 Charlotte Street, London W1 (020-7580 6464; www.rokarestaurant.com).
An unforgettable place I’ve travelled to in the past year is Lake Tahoe. It has a surface elevation of 1,897m, half of which is in Nevada and half in California. It’s the most beautiful place I’ve visited in a long time. You drive through the desert and then there is the lake, with its crystal-clear water and lush vegetation framed by mountains. It looks like Switzerland.
An object I would never part with is a vintage Rolex watch given to me by my father when I was a teenager; I don’t know the precise year or model. He has one, too, but no longer wears it. www.rolex.com.
My favourite website is BBC News, which I am addicted to. I don’t watch much television but I love the news. I also have the app on my iPad, which is easy to scroll through and allows you to watch live news by region. www.bbc.co.uk/news.
