A sundress is a garment designed to keep people cool, comfortable and stylish during the hot and sunny days of the summer season. It is usually light, airy and with vibrant colors and patterns that reflect the joyous atmosphere of summer. A summer dress is usually short or medium length, allowing the legs to be exposed and providing a fresh and youthful touch. They often have more open or off-the-shoulder necklines, such as V-necks, halter necks, or Bardot necklines, which are ideal for taking advantage of the sun and highlighting your tan.
