A Ralph Lauren firm that operates a factory outlet store in Kildare Village last year recorded revenues of €179,000 a week.
New figures lodged by the Irish arm of the US luxury brand show the firm made revenues of €9.3m in the 12 months to the end of March 29 2014, a 2pc increase on the year before.
Pre-tax profits for the company - named Ralph Lauren Ireland Ltd - however, declined by 81pc from €784,277 to €144,151. The drop in profit was down to a rise in the cost of sales.
The firm began trading in August 2007 as a factory outlet store in Kildare Village retail park selling clothing and accessories.
It has become one of Kildare Village's best-known shops.
The firm paid a dividend of €500,000 last year, the accounts show, and is recommending the payment of €500,000 again this year
The number of staff employed by the firm decreased from 54 to 50, though staff costs increased from €706,824 to €743,163.
Separate accounts filed by the Irish outpost of Tiffany, another US luxury brand, show that profits sparkled at its shop on Dublin's Grafton Street after more than tripling to €166,000.
The company's only Irish store recorded average weekly revenues of €76,846 or €3.99m in the 12 months to the end of January 31st 2014, a gain of 17.5pc.
