As the fashion world gets ready for the much awaited Victoria's Secret annual fashion show, the one thing that has definitely grabbed the attention of the masses is the 2011 version of the iconic Fantasy Bra.

This one-of-a-kind customized Gorgeous Push-Up Bra; designed by the world renowned London Jewelers was inspired by an underwater dreamland. Embellished with nearly 3,400 precious gems, the Fantasy Bra has a total carat weight of 279 carat and cost a staggering $2,500,000.

Selected for wearing this year's creation is supermodel and VS Angel Miranda Kerr.

It's such an honor to wear the bra, People magazine quoted Kerr as saying, And it's such a piece of artwork! It's absolutely stunning -- it kind of feels a little mermaid-like -- but I can't believe I'm wearing $2.5 million on my chest.

The Fantasy bra is regarded as one of the more important aspects of the Victoria's Secret annual fashion event. Typically, Victoria's Secret selects a single supermodel to display this unique, bejeweled bra during the show each year.

Although the bra was initially showcased only in VS catalogs, the luxe lingerie brand decided in 2001 to begin showcasing it during the annual fashion shows as well.

Victoria's Secret Angels who have donned these designer creations include Gisele Bundchen, Tyra Banks, Karolina Kurkova and Adriana Lima. However, the highlight of the list must surely be Heidi Klum, who has worn the Fantasy Bra in three different years.
