Peter Som, who went heavy with skirt suits in his fall collection, says he recently attended a wedding, where the woman wearing the tuxedo suit got the most attention from the opposite sex. She accessorized with strappy Manolo Blahnik stiletto sandals and a clutch purse - and nothing underneath her impeccably tailored jacket. "You want that look of effortless ease," he says.

It is pretty easy: "It is practically a uniform," Som says. "Ultimately there's a very strict template, and that's appealing to almost everybody."

Designers who infused their fall runways with a hint of Savile Row include Dolce & Gabbana, Prabal Gurung, The Row, Tommy Hilfiger and Ralph Lauren.

"Fit is No. 1," adds Som. He advises nothing too loose or too baggy, a defined waist and a perfect hem on the pants.

Som picks out Carolina Herrera, who almost always wears a crisp white menswear-style shirt to take her bow at the end of her fashion shows, as someone who always gets the look right.

It's the wearability of this style that gives it broad-based, long-lasting appeal, says Joanna Coles, editor-in-chief of Marie Claire. She says she wouldn't call it trendy because it's really built on longevity, but the blazer is a must-have item of this season.

She likes it best with the sleeves pushed up above the elbow, giving just that little glimpse of skin. "I like that it can be masculine, androgynous and feminine all at the same time," she says.

Miller says she'll often put together - both on the runway and in her personal life - a very girlish dress with a jacket. A similar pairing of a tuxedo jacket and a beaded miniskirt also works great, she adds.
With celebrities commonly labeled as either good or bad role models these days, the controversial reality TV star and England's popular new royal stand at opposite ends of the spectrum of whom young people should strive to emulate. Like their cartoon counterparts, Goofus and Gallant, the SoCal party girl consistently behaves in a manner that should not be copied by young people, whereas the pretty princess is pointed to by parents as the epitome of proper young ladyhood.

If any two specimens of celebrydom convey the extremes in behavior of the rich and famous, the round- bottomed publicity seeker and the more private, pretty princess, are it. Here is how each plays the roles of good and bad role model.
