A sheath by definition (think about the sheath of a sword, for example) is meant to hold close to that which it encases. The neckline can vary, but a fitted waist is the focal point of this type of dress. Sheaths are also often sleeveless, and when they are longer than mid-thigh, a slit up the back makes it easier to walk in. Because of its rather broad definition, the sheath dress can take on many forms and can also be dressy or casual, depending on the fabric and cut. Shorter sheath dresses are great for parties and cocktail events, while a longer dress in a more conservative cut is a staple for the office. Sheath dresses were popularized by American designers like Narciso Rodriguez, Donna Karan, and Ralph Lauren, who favored minimal, uncomplicated designs in the 1990s, but the style has roots as an undergarment going as far back as the early 1900s.

In the summer you can skip the jacket and accessorize with a structured work tote and simple stud earrings.
