It might be the most impractical bra ever made, but that doesn't stop us from marvelling at the Victoria's Secret Fantasy Bra year after year

What happens when you place a bra worth over one million dollars on one of the world's most beautiful models? A moment of pure PR genius that money can't buy, that's what. Marked as the pinnacle of the now-annual Victoria's Secret show, the diamond and precious jewel encrusted Fantasy Bra is one of the lingerie giant's more curious creations. First introduced in 1996 and modelled by über-babe (and original super) Claudia Schiffer, the US$1 million bra was front and centre of the Christmas catalogue.

Since then, the price tag has fluctuated (perhaps to reflect the economic market?) anywhere from US$2 million in 2014 to an eye-watering, record-smashing $15 million peak in 2000. Worn by busty and leggy Victoria's Secret alumni like Tyra Banks, Heidi Klum, Gisele Bündchen, Karolina Kurkova, Miranda Kerr and Candice Swanepoel - the list of lucky beauties also reads like a barometer of the hottest models at the height of their careers.

While 2014 saw two VS Fantasy Bra favourites - Brazilians Adriana Lima and Alessandra Ambrosio - take the mantle for the first time ever, this year's golden girl Lily Aldridge dons the $2 million Firework Fantasy Bra for her own solo spotlight turn. We wonder if anyone will snap up the bra for real this year? To date, only two bras from 2004 and 2012 respectively have been snapped up by (most-likely) red-blooded male admirers hoping to impress their wife or girlfriend (we hope).

Stay tuned for coverage of the 2015 parade and in the meantime, see how Australia's own VS first timer Bridget Malcolm got in shape for the parade.
