Trends come and go, but certain looks persevere well past their inception. They become mainstays of the male wardrobe, mainly because they're simple, straightforward and less prone to changing times than things like, say, leisure suits or Ed Hardy tees. Take a look at these 10 style icons who exhibited their own timeless looks, and feel free to adjust your own closet accordingly.
1. Muhammad Ali: He was at his best in a pair of gloves, but the simple tailored suits and slim ties Ali donned outside the ring reflected the class and attention to style of his era.
2. James Dean: Dean didn't need his iconic leather jacket and boots for his inherent cool to shine through; a pair of worn-out sneakers and loose slacks worked just fine.
3. Jack Kerouac: When you wander as much as Kerouac did, there's not much time for stylish suits and accessories. His wardrobe often consisted of whatever he could fit in a backpack, and it was that bare-essentials approach to life that fed his effortless look.
4. Michael Caine: Of course, there's nothing wrong with wearing stylish suits and accessories, as Caine demonstrates in this photo from his early days in the limelight. A beautiful woman hanging off your side never hurts either.
5. Marvin Gaye: He could rock a tailored suit whenever he wanted, but Gaye's greatest contribution to style was his casual wear. Few men have ever worn denim shirts quite as well as he did.
6. Paul Newman: Newman ranks right up there among Hollywood's all-time coolest. Aside from starring in some amazing films (and producing some equally amazing salad dressing), he demonstrated how to turn a few simple pieces into a kickass personal uniform that reflected his character and contributed to his lasting influence.
7. Bruce Lee: To be clear, Lee was one of a very small handful of men throughout history who could wear a shirt like this one. The thing to take away from his bold choice of apparel is that confidence is the key to any outfit. Of course, confidence comes pretty easily to a guy who can kick a person in half, but you know what we mean.
8. Steve McQueen: Whether he was jumping motorcycles, racing cars or starring in Hollywood classics, McQueen never had a day when he didn't look like the coolest guy in any room. Key takeaways: basic sweaters, fitted button-downs, earth tones and the ability to impregnate a woman with your eyes.
9. Johnny Cash: Cash dressed the same way he played music: pared down, to the point and always true to himself. His simple black suits were as conservative as they come, which meant his songs were the center of attention when he got up on stage. It sure doesn't hurt that they're damn good songs, of course.
10. Woody Allen: As one of the most prolific and active filmmakers in the industry, Allen doesn't have a whole lot of time to stand in front of his closet in the morning. That shows in his style, which hasn't changed a whole lot since the early '70s, and demonstrates the practical benefits of picking a personal uniform and sticking with it.
