The shop is the 4000th globally to bear the famous red H&M logo.
Covering 37,000 sqft (3437 sqm), the store has four floors, each devoted to apparel and accessories for women, men, teenagers and children respectively.
H&M country manager Janne Einola, area manager Mikko Alatalo and store manager Varun Pratap Singh cut the red ribbon to officially open the store.
A queue formed ahead of the opening, with the first 10 customers receiving a gift card worth Rs 4000 (US$60), while the next 200 in the queue each received a goodie bag and gift card worth Rs 500.
DJ spin-offs were a feature of the launch, as well as dance and fashion contests for the customers.
Parineeti Chopra was clearly impressed: “I’ve always liked H&M’s exciting and affordable fashion- there is plenty of inspiration in store to create your personal style. The opening was incredibly fun!”
