Key Piece: Track Pants
WHO: Simone de la Rue, 37, personal trainer and owner of Body by Simone
THE INVESTMENT: Gucci track pants, $995 (gucci.com).
WHY IT'S WORTH IT: Finally, workout pants you can truly wear all day! These silky pants are so comfortable, versatile, and on-trend: Wear them at the gym or dress them up with a special top or jacket, jewelry, and heels.
It seems counterintuitive, but high-performance gear with high-wattage shine is the perfect balance of casual and glamour. Look for tops that have the feel and cut of a sweatshirt but with star quality in a light-reflecting silver.
Paint fingers and toes in scarlet for a hint of sex appeal. Strappy heels are a must.
