Wanted: More Waist

"I'm not looking for traditional business attire; I want a nice, sexy spin," says Sil Lai Abrams, 37, author of No More Drama and relationship columnist for Men's Fitness. Khakis teamed with tweed (jacket, Rena Lange) have office-ready authority; take them into evening with enamel bracelets (Roxanne Assoulin for Lee Angel), a waist-emphasizing belt (Pellemelle), and shoes (Via Spiga). Top, Lela Rose, $420.
