Ageless Advice from Some of Our Favorite Designers

"Keep your jacket buttoned. Always. It's just really flattering—it will take pounds off you."

"It's simple: Everyone should have a black blazer."—Domenico Dolce

"The best style advice came from my parents: Be honest. Just be yourself."—Stefano Gabbana

"I believe one can live many lives through personal style. Every day is an occasion to reinvent yourself."

"People shouldn't notice what you're wearing before they notice you. You want people to register you first. 'Oh, what a nice jacket' should be an afterthought if you're doing it right."

"It's good to be rather unsentimental about your grooming. I use one spray of fragrance and that's it. Don't think too much about it; just get on with it."
