For a woman in her 40s, Stacy chooses a ladylike dress ensemble by 3.1 Philip Lim, available at Nordstrom, that emphasizes the waist while camouflaging problem areas. "In your 40s, that's when things start to spread, right? Your hips, your arms start to sag. The girls go south," Stacy says. "The idea is that this is still a flattering silhouette, still waist-conscious."
The main thing for a woman of any age to focus on when buying a "ladylike dress," Stacy says, is the waist. "This is a trend that you're going to see season and season again," Stacy says. "The idea here is that you want to show off your curves. If you pay attention to your waistline, you will always have a flattering silhouette. That is what works for women as long as the girls are up there where they should be."
