Mom always said to bring extra layers, and, as usual, she was right. Be functional and fashionable by layering a long cardigan, leather jacket or blazer over your little black dress. If you don't want the added bulk, wear a fitted knit shirt underneath your dress and instantly transform it. You can also layer necklaces, bracelets or rings, but not all at once; there is such a thing as being ostentatious.
The simple style of a little back dress can be drastically changed with a few coats of nail lacquer. Embrace the old adage that black goes with everything and consider the full rainbow of possibilities. Think about what style you're going for -- a matte hot pink nail color creates an entirely different look than a deep crimson red. If you're wearing sandals or peep-toe shoes, wear color on your toes. Mandatory matching manicures and pedicures are a thing of the past, so double the fun and wear a different polish on your hands and feet.
If you want to spice up your little black dress, look to your legs. Experiment with sheer, patterned, colored, lace, textured, shimmered and opaque leg wear. For a more seductive look, consider a mock seam stocking; a single seam up the back of the leg goes a long way. If your outfit isn't too heavy on jewelry or embellishments, try a flashy pair of stockings that have a bold pattern or a sparkle woven in.
To stand out from the crowd, pick accessories that make a statement. Chunky chains, big pendants, shiny jewels and vintage necklaces all add a little something to a little black dress. Experiment with belts of different sizes, patterns, and textures, which are both form-flattering and eye-catching. If the occasion is casual, don a casual boot or flat; for a more formal affair, consider silk scarves, printed pashminas or cozy shawls.
