Brown Thomas in Dublin's Grafton Street and Arnotts in Henry Street will fully reopen on Wednesday June 10 as part of the Government's revised phasing for reopening society and business.
Brown Thomas said its regional stores in Cork, Limerick and Galway will fully reopen on Thursday June 11.
The shops' new opening times will be from 10.30am to 6pm.
The company said it has been planning the safe reopening of its stores for weeks and all necessary safety measures will be implemented before opening in compliance with government and HSE guidelines.
Customers will be able to pre-book visits into the stores via the Brown Thomas and Arnotts website with walk-in visits to be facilitated via a queuing system if necessary.
"Virtual" queues will also be in place, whereby customers can join a queue virtually and receive a text message when they are at the top of the virtual queue and can enter the store.
Both Brown Thomas and Arnotts will operate at a reduced capacity and the number of customers in each shop will be electronically counted on entry and exit and displayed on screens for customers to see.
The retailer said that to ensure customers can receive the best beauty expert guidance, new larger consultation areas have been created to allow for social distancing.
A "no touch" policy will be in place on beauty products with testers available to view only.
Technology is now available to allow customers to virtually "try on" make-up, there will be no staff contact with customers at make-up counters and no self-service tester brushes.

There will also be a free same-day home delivery service for customers who buy some larger items, to avoid them bringing them on to public transport and potentially into contact with the wider public, while a new click & collect area has been set up in the Brown Thomas Dublin car park so customers can remain in their car to collect their purchases.
Customers can still use fitting rooms and all clothing will be steamed and sanitised if it is tried on.
Donald McDonald, Managing Director of Brown Thomas Arnotts, said that customers will experience some differences in how things are done as we ensure the highest safety and hygiene standards are adhered to.
"But we are confident that our customers will enjoy the new innovations that we have introduced, which will make their shopping experience as seamless and enjoyable as ever," Mr McDonald added.
