Work a white dress the right way -- with the perfect lingerie. Keep in mind the color and texture of your undergarments, as a white dress requires a smooth and seamless appearance underneath. For the best results, eschew the frills and stick to simple lines and neutral shades.
Contrary to popular belief, white lingerie is not your best bet beneath a white dress. The effect can be what "Real Simple" magazine calls a "double opaque effect," where the white underwear and white dress combine to look more opaque than the rest of your dress. Opt instead for a nude shade, choosing a color as close to your skin tone as possible. This creates a seamless, "nude" effect underneath your dress that won't show through. Another option is to wear a slip -- half or full-length -- to ensure that what lies beneath your dress looks all the same shade, even beneath a very thin white dress.
Keep it simple and stick with smooth-textured undergarments. Bras and panties with ridges and ruffles tend to show up more easily underneath a white dress, which doesn't have the camouflaging powers of a garment in a deeper shade. Smooth shapewear can be helpful, as it hides body lumps or bumps. Pull on a mid-thigh shaper, camisole or even a full bodysuit in a color that resembles your skin tone.
