Let’s face it. Not everyone has perfect proportions no matter how hard you work out. Hour glass-shaped women quite often desire to make their hips look slimmer and legs look longer. Rectangular shaped women who usually have long beautiful legs desire to make the waist look thinner. While wearing all black might make you look few pounds lighter, the current trends enable a great choice of dresses with structural design and a pattern which creates the optical illusion of changing size. I absolutely love these dresses.
