The Victoria's Secret Fantasy bra the 25-year-old Jasmine Tookes was selected to wear is considered the piece de resistance of the brand's runway display.

The bra, glimmering with thousands of gemstones, was presented like crown jewels ahead of the show. An incredible work of art, it was designed by Eddie Borgo and handcrafted over 700 hours with gems from jeweler AWMouzannar.

"It is so beautiful. It's covered in white diamonds and emeralds and it has about 9,000 gemstones. It cost $3 million - so stunning," gushed Tookes backstage while she was having her hair done.

It's the third time a black model has been chosen to model the Fantasy Bra.

Tookes says the garment was constructed on a mold of her upper body, literally made to measure.

While the bra may be perfect for the runway presentation, Tookes joked she probably wouldn't want to go for a jog in it, given its weight.

"It's very heavy; it weighs more than 450 karats. It weighs down on my shoulders a little bit, but it's so worth it," she says, cheekily adding: "I might jog out of this show with it though."
