The new Belfast outlet of Peacocks is set to be the firm's largest Irish store and will create 16 jobs in the city, it was announced.
The arrival of Peacocks to Belfast city centre was exclusively revealed in Business Telegraph last month.
The 14,000 sq ft outlet, described as a "flagship" branch, will be opened tomorrow by Miss Northern Ireland Lori Moore and will sell value clothing and accessories for men, women and children.
The three-storey complex at Donegall Place takes the place of leisurewear chain Esprit, which closed two months ago. Esprit had replaced Top Shop, which moved to Victoria Square in 2008.
It will be the 24th Peacocks store to open in Northern Ireland.
The announcement of the new shop flies in the face of recent warnings that high cotton prices will spell an end to cheap fashion.
New store manager, Susan Temple said the new shop will offer bargain hunters value for money in the tough economic climate.
"We're delighted to be opening our new store in Belfast, offering customers the latest looks at great value," she said.
"With fashion changing so quickly it can be a challenge to keep on top, but with over 30 new lines landing in our new store each week it should be easier for customers to step out in the latest fashion and not break the bank."
The shop will be the only one in Ireland to offer Pearl Lowe for Peacocks Christmas 2010, a 10-piece vintage fashion collaboration from designer, Pearl Lowe, her fifth collection for Peacocks.
All the items on sale will be under £60.
Peacocks is one of a number of low-price retailers to set up shop or expand existing services in Northern Ireland this year.
Poundworld and B-amp;M Bargains have also announced new branches across Northern Ireland in recent months.
Albert Frank Peacock founded Peacocks in Warrington, Cheshire in 1884 as a Victorian penny bazaar.
In 2002 the Peacock Group acquired value retailer Bonmarche.
