Asos’s head of womenswear design Leandra O’Sullivan will move to Debenhams to take up the same role in May.
O’Sullivan joined Asos in January 2011 and previously spent five years as head designer at Monsoon Accessorize from June 2005 to December 2010.
Debenhams said O’Sullivan’s remit will fall under womenswear divisional trading director Sara Stern. She will work alongside head of design Russell Fish.
Asos has not yet confirmed if a replacement will be appointed.
