Dress 10 Pounds Slimmer!

After: Fit and Flare

Soft inverted pleats on the neck and skirt of this smart A-line (Talbots, $179) generate the illusion of length; a thin belt in a tonally related color (Kristin Kahle Designs, $96) subtly and smoothly marks the waist. Not-too-shiny metallics (shoes, Stuart Weitzman) are more fun than the usual summer neutrals. Bracelets, House of Lavande, $548 and $350; 561-802-37. Shoes, Stuart Weitzman, $325; 310-860-9600.

Tip: Pleats ensure an easy, unconstricted feel; a skinny belt exercises curve control.
