HOW TO PICK OUT MEN'S JEANS: Men's Health gives some advice so you don't end up getting ridiculed like President Obama and his "Dad jeans."

The perfect pair of jeans for you: The perfect blue jeans are the DNA of a man's casual wardrobe. They take the million random possibilities of style and organize them into a coherent system. So pick a classic pair, like dark denim. They're versatile in a way well-worn jeans are not. Indigo jeans are cool with a plain T-shirt and sneakers, but clean-cut enough to hold their own with a dress shirt and tie or a casual blazer when occasion calls. Choose a pair that fits low on your hips (below the navel), and make sure they're straight-leg or boot cut. (The tapered look repels ladies.)
How to get a pair that molds to your body: No pair of pants looks better on a man than blue jeans that were stiff and dark when they came home from the store and have been softened and sculpted and battered against his body by life. Buy a single pair that starts out looking like something Potsie wore on Happy Days. Over time, they'll mature into your favorite pair. Hers, too.
How to tell if your pair is too baggy or tight: I call it the anatomy test. If I--or you--can see any of your frontal anatomy through your pants, they're too tight. If we can see any of your gluteal anatomy above your jeans, they're too loose. Please leave the extra-baggy jeans for rappers, skate punks, and Weight Watchers commercials. And trust me, no one wants to see a man in tight jeans. Ever.
How to make jeans go with everything: Blue jeans, which by rights ought to be casual, have evolved into the ultimate in flexibility. Used with wit, they can work in many different situations. For example, though in most venues you shouldn't wear blue jeans (casual) with shiny slip-ons (somewhat formal), there are certain urban, art-gallery moments and late-summer cocktail-party-on-the-deck situations in which jeans and fancy loafers are okay, assuming of course no socks are involved.
The jacket to wear with jeans: The full-denim outfit is a little too country for most gals. Instead, add a buttery suede or leather jacket.
