Monsoon Accessorize has recruited from inside the business after its international boss was poached by Mothercare.
Harriet Poppleton was formerly international franchise and business development director, a role she had held since September 2016.
She worked at Monsoon as an international regional controller for eight years from 2006 and then rose rapidly through the business.
Monsoon is currently mid-way through a turnaround plan. It has struggled in a tough fashion market recently, deciding to close about 141 dual fascia stores over the next five years and instead run the two businesses as separate entities.
In May it reported that EBITDA had plunged 59% to £19.3m in the year to August 29, 2015. Total sales in the period fell 8.6% to £434m.
Monsoon did not disclose a like-for-like sales figure.
Overall, Monsoon recorded a net loss of £617,000 for the year, compared with a profit of £18m the prior year.
It installed Paul Allen as its permanent chief executive in January, nearly a year after he became interim boss.
Allen, who joined Monsoon in 2013 as finance director, took over from John Browett as its chief last February.
