Our exclusive behind-the-scenes video lifts the curtain on the fittings for the upcoming Victoria’s Secret Fashion Show. Between struts and giggles, two separate two-million-dollar-gem-dazzled Fantasy Bras, and a whole lot of feathers, sequins, and structured underpinnings, our favorite faces, including Adriana Lima, Alessandra Ambrosio, and Karlie Kloss, give us a sneak peek at next month's lingerie extravaganza. (Warning, this video may induce bombshell-body envy.)
