El Corte Ingles in Mijas has doubled the number of its shopping floors from three to six.
The additional levels will open on Thursday (November 12), bringing dozens of new brands to the department store.
The expansion increases retail space from 14,500m2 to more than 22,000m2.
The company says the project has created 223 direct jobs, taking the centre’s workforce to more than 500.
New additions to the womenswear department include Calvin Klein, Guess, Donna Karan, Karl Lagerfeld, Brownie and Simorra, while accessories shoppers will find Pandora, Swarovski, Aristocrazy, Liu Jo and Parfois.
Menswear arrivals include Polo Ralph Lauren, Hugo Boss, Tommy Hilfiger, Silbon, Scalpers and Roberto Verino.
The beauty department is adding Dior and Jo Malone, alongside brands from the Estee Lauder and L’Oreal groups.

Sportswear will include Nike, Adidas, Under Armour and On, while the children’s department gains brands including Mayoral, Gocco, Polo Ralph Lauren and Tommy Hilfiger.
Home appliances also feature in the expansion, with Miele, Smeg, Dyson, Jura and Ninja joining the offer.
The opening follows a series of changes over the summer, including the launch of a Club del Gourmet, an updated Hipercor food shop with a prepared-meals section, and a refresh of the Unit Home furnishings and decoration department.
The complex has 1,733 parking spaces, alongside services including a travel agency, optician, dry cleaner, vehicle workshop and car wash.
El Corte Ingles estimates the centre serves more than 250,000 residents in the surrounding area, rising to as many as half a million people during busier periods.
