Every season, a few of-the-moment colours take precedence in fashion and interiors. This season, it’s everything from chartreuse to Cadbury purple. One shade bubbling up that we expect to see everywhere is International Klein Blue. Created and officially registered by French artist Yves Klein in the 1950s, the shade somehow feels so modern and cool in 2026. Scroll to shop our favourite pieces in the hue, from lightweight jackets to cute tops.
