These knee-length dresses include a design for every occasion, from a holiday in the sun through to days at work. Figure-framing silhouettes in soft tones and florals, cut from lace, silk, tulle or jacquard, are refined and ideal for formal occasions. Darker hues with elegant detailing lend themselves to black-tie styling. For weekday looks, simple shifts and shirt dresses combine the chic with the informal, while sleeveless and off-the-shoulder styles in vibrant patterns capture a playful off-duty spirit.
