TEAM LBD'S TOP TIPS FOR DRESSING SLIM -The easiest of all slimming rules: good posture. Hold your head up, shoulders back and tummy in for an instantly longer, leaner shape. -Invest in shapewear. With a nipped and tucked body beneath dressing yourself down a dress size is easy. -Show off your best assets. Love your legs but hate your waist? Flash perfect pins in a sexy mini dress and no-one will be looking above your hemline. -Choose shoes wisely. Ankle straps create a horizontal line that cuts you off at the leg. Instead opt for elongating nude shades or open-toe high heels. -Accessorise. A chunky necklace will distract from a muffin top and an over-sized bag will make you appear smaller.
