Greenwoods Menswear & Suit Hire, which was founded in 1860, has gone into administration.
The company, which has its headquarters in Bradford, has 63 stores across the UK, including a store in Bangor.
Administrators Deloitte said they were “assessing options” and no redundancies had been confirmed. It will continue to trade for the immediate future, a spokesman said.
Adrian Berry, administrator, said options included the sale of the business. He added: “No redundancies are being announced at this stage and we are grateful to the employees for their support at this difficult time. This is a challenging time for the UK retail sector, which has affected the company.”
