For more than 20 years, Victoria’s Secret had bolstered its image built on a man’s vision of sexiness with one big annual event: its fashion catwalk extravaganza, with supermodels like Naomi Campbell sashaying down the runway in Swarovski-crystal covered wings, thongs and million dollar fantasy bras. Now, after a four-year hiatus, the lingerie brand came back Wednesday night with a complete overhaul that was part fashion event and part preview of a documentary-style film featuring 20 global creatives. The Victoria’s Secret World Tour, to be aired globally on Amazon Prime Video on Sept. 26, marks the company’s biggest marketing investment in the past five years and its latest efforts to reverse its supercharged sexy image that left it irrelevant to many women, leading to several years of sales declines.
