The store, which will open its doors on April 3, covers 12,120 square feet and will stock womenswear, menswear, footwear, accessories, and 915 ranges.
The opening will be celebrated until April 5, with goody bags given out to the first 200 customers each day who spend in store.
Free treats, including coffee, bubble tea, and pink hot chocolate, will be handed out with every purchase.
Surprise gift cards will also be hidden around the shop for customers to find, and a DJ will perform.
Customers who spend £50 will be in for a shot at winning prizes from the in-store claw machine.
One lucky customer each day will also win a free haul of everything in their shopping bag.
Elaine Cartwright, retail director at New Look, said: “We’re thrilled to unveil our new Bluewater shopping centre location, a space designed to seamlessly blend our digital expertise with the best of in-store shopping.
“By integrating cutting-edge technology – such as dynamic digital displays, enhanced in-store merchandising, and convenient Click & Collect counters – we’re making it easier than ever for customers to discover and shop our latest feel-good fashion.
“This state-of-the-art store builds on the success of our Manchester trial, where digital innovations drove a significant uplift in sales and resonated strongly with our customers.
“We’ve seen first-hand how the right balance of digital and physical retail can enhance the shopping experience, and we’re excited to bring this next-generation concept to our loyal Bluewater shoppers.”
The expansion will offer more customers the opportunity to discover the quality of New Look products in an omnichannel store, as well as offering online click and collect.
