Alberta Ferretti's days of the week knits are already a celeb favourite

Remember the underwear you had as a teen that spelt out the days of the week? Or perhaps a seven pack of socks were more up your street?

The last place you’d expect to see these daily delights is on a couture runway. Yet that’s exactly what Alberta Ferretti did back in January.

The Rainbow Week capsule collection was part of the designer’s entry into the see now, buy now culture that has overtaken the fashion industry. The candy-hued knits featured vibrant shades of yellow and pink as well as less loud designs in black and grey.

Since they hit the runway, these jumpers have become a cult favourite among celebrities including models Gigi Hadid and Alessandra Ambrosio along with the likes of Amal Clooney and Diane Kruger.
