When Kate Moss showed up to Stella McCartney's London Fashion Week party over the weekend, not only did she stun in her Stella LBD, but she also managed to create a fabulous fashion illusion. How so? Notice how the side panels of the dress are nude, rather than black. This creates mega shape, cinches the waist, and gives the illusion that Kate's bod is super curvacious. Now it's your turn to play a fashion trick at your next fancy soiree, and this Oh My Love mesh panel dress ($49, originally $70) will help you do that. Sure, it's no Stella, but it gives off the same illusion that your waist is tiny. If that one is not to your liking, shop a few other black-and-nude colorblock dresses below.
