Miss Sixty, the high-end fashion retailer owned by Italy's Sixty Group, faces an uncertain future after the UK arm was placed in administration on Monday.

The company - which operates from 12 high street stores across the UK and in concessions in some of Britain's top retailers, such as Harrods and House of Fraser - has fallen foul of an expansion plan gone wrong as well as falling sales in the high street, according to Peter Hollis, partner at Vantis Business Recovery Services, the administrator.
