Lewis Hamilton, 31, the current Formula One champion, has won more grand prix races than any other British driver in the history of the sport. Raised in Stevenage, England, and now based in Monaco, he is defending his title this season, which kicked off March 20. Mr. Hamilton, a phenom who first got behind the wheel at age 8, is a frequent presence at fashion shows, and sports a look much like his racing style: sleek and occasionally flashy.

1 Shirt I don’t mind dress shirts if I have a real posh event to dress up for, but generally, if I can be more casual, I’ll choose to do that. I love some stuff I have from Oliver Spencer. It’s a British brand and I’ve met him through the shows — I recently joined London Collections: Men as an ambassador. His style is just fantastic. It’s very clean.

2 Jeans In Formula One, you have all these big brands involved, so there are very strict guidelines. You have to kind of wear what you’re told to wear. It’s kind of hard to still be yourself in it. That’s why it’s great to be able to come out and be able to show a little bit of your character and what you like and what your personality is when you’re not racing. Such as, I wear jeans a lot. One of my favorites is Saint Laurent, especially the ripped version. It’s slim fit, but not too tight that you can’t move. Black is always safe, but generally I like the denim look with a faded kind of wash.

3 Suit I wear the Hugo Boss tailor-made suits. They’re a sponsor for our Formula One team. I’ve been up to their offices in Germany where they do the perfect fittings, and I get to select all the different fabrics to use, which is great. With a suit, I like more of a classic, clean look. I like the fabrics to be more lightweight. I don’t like it to be too hot or too tight. I chose to wear gray and black today because it’s classic and casual, but I’m often in lots of different colors. I love wearing color.

4 Accessories If you’re wearing something simple and gray, you’ve got to set it off with certain things. I wear it with a watch and bracelets to make it pop off. These are Cartier bracelets, which have diamonds, that I wear all the time. One is the “nail” bracelet and the other is a “Love” bracelet. They say, “Diamonds are a woman’s best friend.” I disagree, because they can be the same for men. I’m probably the only man in my sport who wears diamonds.

5 Shoes I love sneakers. I wear more of a sneaker than a shoe now. There’s a Berlin-based brand, Patrick Mohr, whose styles are pretty cool. They have great texture and shapes on the side, and he uses rose gold. They also have quite long laces and quite a big, full tongue. I found them on Instagram. I follow sneaker websites and Instagram accounts to see what’s going on.
