The LBD is a wardrobe staple, which makes it all the more important that you feel more attractive than Victoria Beckham on the arm of David Beckham while wearing it. A mesh panel in the waist smooths out any would-be muffin top, so you're svelte without sucking in.
Work, errands, shopping, the occasional party...no matter what you've got going on, these styles will have no problem keeping up and keeping you looking up-to-date.
