To give the illusion of a longer leg, try neutral pumps in skin-tone colors. If you match your shoes as closely as possible to your skin tone, there's no abrupt ending to the leg, and so you can look taller and also slimmer. An added plus: neutral colors go with anything, so you don't have to worry about whether or not your shoes will go with your clothing. As far as the style goes, sleeker styling works better for petite women.
D'Orsay styling gives these neutral suede pumps an open feel that's nice for spring and summer. Other flattering features include a peep toe and slim 3" high heel.
Bronze strappy sandals give a metallic tweak to brown for petite women who have a dark skin tone. These pumps have a heel height of 4", and they come in sizes as small as women's size 5.5.
