A shift dress is high on comfort because it doesn't fit too tightly; at the same time, it does lack a certain definition in the waist. Wearing a belt over your shift dress can give it shape and add a pop of color or pattern to your outfit. Choose a thin or medium-width belt to create the most balanced appearance. If your shift is a neutral color, opt for a belt in a bright shade like red, purple or cobalt. A striking animal print or metallic belt is another ideal option. For a shift in a bold color like lemon or tangerine, choose a belt in a shade from the same color family with a patent leather finish -- you’ll have a sleek monochromatic look, but the belt’s shiny texture will help it stand out.

A simple shift dress makes an ideal layering piece, and you can easily dress it up or down for any occasion. For the office, wear a fitted blazer over a jersey shift dress to help define your waist. Pair the combination with pumps for a polished, professional look. You can also wear a belted, slim-fit cardigan over a tweed dress when you’re headed to work. If you want to wear your dress more casually, layer a denim jacket over a cotton shift and add ballet flats or flat boots for a relaxed weekend outfit. You can also give a simple satin shift dress an edgy vibe by layering it with a leather jacket and adding moto-style boots.

Statement jewelry can help give a simple shift dress a little more personality. A dramatic bib necklace with brightly colored enamel pieces or stones is an ideal option over a cotton or jersey shift with a high neckline. If you’re wearing a satin shift to a formal occasion or cocktail party, try a rhinestone choker. Bold earrings like beaded hoops or a chandelier style in colorful crystals can also work well. If your dress is sleeveless or short-sleeved, try an armful of bangles or a single cuff bracelet to help spice up its look.

If your shift dress is on the shorter side, try wearing it over a pair of leggings to give it a tunic-like look. Black leggings are a classic option, but if your dress is a solid neutral color, try floral or animal prints for a little flair. For a casual outfit, wear ballet flats, gladiator sandals or moccasins with a cotton shift and leggings. If you prefer a more polished look, slip into knee-high boots instead.
