British fashion designer Clare Waight Keller, known for her sophisticated, effortless aesthetic, has launched a new collection with retailer Uniqlo that centres around a major trend for the season: pops of primary colours.

Vibrant shades of poppy red, aqua blue and forest green are cleverly interwoven with pastel pink pieces and plenty of neutrals for the designer’s second Uniqlo:C collection (the first drop of which is in stores now and the second drop launches on 12 April).

The collection focuses on light, comfortable and practical separates, dresses, outerwear and accessories that are effortless, versatile and fit into women’s everyday lives. Waight Keller says: “Part of the collection philosophy is that it’s all about women on the go, and it’s about pieces that really transition to every part of the day and also in your lifestyle. I’ve really worked with Uniqlo a lot on the fact that things need to be super-easy for women, so everything here is machine washable; it all has this amazing trans-seasonal quality to it.”
