10 Tips for the Stylish Gent

Natty British designer Paul Smith outlines his do's and don'ts for the 21st-century gentlemen in a cagey Details interview. Cologne lovers, beware:

1. T-shirts seem easy, but they're a big no-no; go with a collar.
2. A good, bland haircut is better than a failed stylish one.
3. Women first! Don't ignore them in favor of a pal at dinner.
4. Dress for the occasion, but chuck the bow tie if no one else is wearing.

5. Older men can swing a full beard; just don't try artful stubble.
6. Take a cue from Londoners: They value free-thinking over style.
7. Take notes from innovative dressers, too, like Daniel Day-Lewis.
8. A custom suit is comfortable enough for everyday wear.
9. Tech, like cell phones, mucks up the lines of your suit.
10. If you use cologne, go easy, guy.
