Look for inspiration all around you. "I don't really have a famous actor who I find really fabulous. It's really people that I know, people that I work with, people that I see in the street. You can get inspired just by walking around and seeing how people are dressed, going to an exhibition, things that people bring into the studio, a conversation with somebody."

Experiment with elegance. "I think sometimes for a guy it can be fun to try a tuxedo jacket. Play around with it—mix it with a sweater or dark jeans. Try what works for you and see how people react. It's really about playing around."

Wear sneakers with a suit. "A really easy way to give more energy to a look is a pair of trainers that are colorful or have silver or gold accents. If you wear a suit with trainers, I think you just look cooler. It's also not like you have to buy a whole new outfit. It's about introducing a new element."

Jewelry is fine, as long as it's manly. "Last season, all of a sudden, we did a lot of jewelry. It was all metal and leather and bolts. It was masculine, and I think that was really the key word."

Fit is everything. "A lot of men don't really know or feel uncomfortable about their perfect fit. Have a good critical look in the mirror, and ask advice from other people, like a shop assistant. You have to know what works for you so it's not too big or too tight."

Play with texture. "It's very important to get less uniform, to dress more individually, and to mix different textures. Even if you wear a suit, you can wear pants of a different texture in the same color scheme so you get different kinds of navy and black. A more textured fabric next to a sleeker or drier fabric creates depth."

Be bold. "Men today are less afraid to try out new things. Things are less about logos and brands, and more about the clothes. People are really wanting to be more individual and and less corporate and less uniform, and they need to have pieces that last—pieces that are more personal."

Show your personality. "I like when I see somebody wearing Lanvin who has made it their own--when they've mixed it up with something they've had for 10 years, like an old, shabby raincoat. For me, the worst thing you can do is go all the way and buy a total look. Clothes are there to underline a personality, not to take it over."

Your home should reflect your individuality, too. "The same principle applies to interiors. It has to be really personal. I have a lot of presents from friends and artworks that I buy. There has to be a story to these things—I have to have a relationship to them."

Travel light. "I try to pack the least possible. I hate waiting for my baggage to arrive. Functional, versatile pieces—two jackets, jeans, more tailored pants and shirts, some ties. Basics.

A true break means no responsibilities. "For me, vacation is not really traveling, in the sense that you have to go places. It's setting yourself off from your day-to-day obligations. Sleep if you feel like sleeping and cook if you want to. Create an environment where you can do what you want to do."

A Few of Ossendrijver's Favorite People and Places

Bryan Ferry
"For me, he's a No. 1 style icon. He looks so classy and so effortless."

Maarten van Severen
"He was a Belgian furniture designer. What he did was very minimal, but at the same time there was something new about proportion."

De Jordaan, Amsterdam
"It's an area that has lots of secondhand stores and small antique shops. The good thing about Amsterdam is you can do everything on foot."

The Rodin Museum, Paris
"A few weeks ago I went for the first time and was stunned because it's such a beautiful museum, and so old."

The Seychelles
"You go to this one island and have your own little house. You can go diving or swimming. You're completely isolated. I really love that, to be completely cut off."
