Jack Wills creative director Sarah Holme has handed in her notice after seven years at the preppy young fashion retailer.
Holme, who joined from Abercrombie & Fitch in 2006, has not set a departure date although it is thought she has earmarked early next year for her exit.
She will remain on to complete current projects, as Jack Wills starts looking for a replacement.
A spokesman for the company said: “Sarah has worked closely with us in building the Jack Wills brand and we are grateful for all she has done during her time with the business. Sarah will remain with Jack Wills to ensure a smooth handover to her successor, who we expect to appoint in the near future. We wish Sarah all the best for the future.”
It follows a wider management shake-up in May by Wendy Becker, who joined as chief operating officer last year and was promoted to chief executive last month.
In May, international boss Tim Patten, sourcing chief Glen Tinton and human resources director Helena Feltham left the business.
Finance director Paul Woolf and head of UK stores Liz Hall also departed at the start of the year.
