The Sia skirt by Copenhagen-based brand Birgitte Herskind combines a tonal aqua blue with a sleek, silky fabric for a grown-up take on wearable colour. It is finished with a black elasticated waistband and a generous cut, allowing the fabric to flow and move with the body. Team with bright white, beige and grey for a stylish wintry palette, or warm it up with florals and richer tones of blue for a considered daytime look. 100% Viscose. Dry clean only.
