Choose a handbag in proportion to your body. Square shape bags flatter a round figure and  a round shape will flatter a square figure. Be sure the strap length doesn’t fall near a trouble area giving you volume in the wrong place.
Use soft, light weight layering pieces to lightly camouflage, not cover you up.
High heels will give you more length and sleek legs, especially when wearing a pant. Be sure the opening at the ankle is not too narrow. Let the shoe show. Sandals and pumps with a 2 or 3 inch heel will also work.
Dressing in one color  will give a slimmer look but be sure to add color in your accessories or a soft or sexy camisole to draw the eye to the face.
Wear a body shaper. A light weight Spanx will do the trick in smoothing  you out, but don’t go too tight. It comes in a variety of styles and sizes. You can find them on line or in Chico’s or JC Penneys.
Be sure to wear the correct size bra. A larger size that fits properly will make you look thinner and your clothing will drape properly showing only your assets.
