is exiting her namesake label for the third time, it has just been announced.

Sander returned to the label she founded in 1968 in February 2012, taking the reins from Raf Simons.

WWD cites ‘personal reasons’ behind her decision to let go of it again.

‘On behalf of the group I want to thank Jil Sander for her remarkable contribution to the brand over this period,' said Jil Sander chief exectuive Alessandro Cremonesi. 'Her outstanding design and creative leadership have been crucial in reinforcing the brand and positioning it to foster further prosperous growth.'

The spring/summer 2014 collection, which Sander showed at Milan Fashion Week last month, will be the last to be produced under her direction; the in-house team is already working on autumn/winter 2014.

In her review of Sander's final collection, ELLE assistant editor and editor of ELLE Collections Rebecca Lowthorpe lauded the 'quietness' of the designer's aesthetic, writing: 'Jil Sander’s clothes are quiet by most designers’ standards and because of their pure simplicity, they rely almost totally on precision proportions, silhouettes and cuts; a pair of narrow trousers will reveal just the right quota of bare calf; a great length of time will have gone into considering the perfect length of those round-shouldered sleeves; and many prototypes will have been thrown away over the months it took to develop those dresses with plunging deep necklines.'
