It's every heterosexual man's dream come true — Adriana Lima walking the streets showing off her perfect assets in a bra-baring outfit.

And her underwear certainly deserved a good flash, since it cost an incredible US$2 million.

Adriana was modelling the diamond-encrusted bra in New York earlier this week for Victoria's Secret.

Showing off the glittering bra in a pale blue satin gown, which was cut away to reveal her chest completely, Adriana attracted plenty of stares from men and women alike as she stood on the pink carpet.

Designed in collaboration with Italian jeweller Damiani, and containing more than 3,000 jewels, the piece took six craftsmen 1,500 hours of work to complete.

Adriana needed a security team just for her bra, with its incredible 142 carats of white diamonds, topazes and sapphires.

With her incredibly slim, toned figure, it's hard to believe the 29-year-old had a baby less than a year ago, Adriana will star in the annual Victoria's Secret fashion show airing on US channel CBS on November 30th.
