Workers at the La Senza chain of lingerie shops have been told they are to lose their jobs after the company went into administration.
There are four stand-alone shops and four concessions in the Republic and three shops and four concessions in Northern Ireland.
Over 100 staff of UK-based company are understood to be affected.
Staff say they were given the news by administrators KPMG this evening and have been told not to come to work tomorrow, as they will not be paid.
KPMG said it had closed 84 stores and 18 concessions, resulting in more than half of the total workforce losing their jobs.
But 1,100 jobs were saved when 60 of its UK stores were bought by an Arabian retail group Alshaya, which owns stakes in a number of British retailers including Next, Debenhams and Mothercare.
