Marilyn Monroe, even after 50 years of her death, beat actresses including Scarlett Johansson, Mad Men's Christina Hendricks and Sophia Loren to be crowned as the woman with the best bust of all time.
The actress - who appeared in 1950s comedies including 'Some Like It Hot' and 'Gentlemen Prefer Blondes' - was closely trailed in the cleavage league table by TV presenter and host of the show 'This Morning', Holly Willoughby, often lovingly nicknamed Holly Willoughbooby.
British actress and model Elizabeth Hurley came third, followed in fourth place by voluptuous Kelly Brook, who recently designed a New Look clothing line for women with more realistic figures.
Italian septuagenarian and screen Icon Sophia Loren came fifth on the list, with Vicky Christina Barcelona star Johansson, Hendricks and singer Beyonce placed sixth, seventh and eighth respectively.
The poll was collated by high street retailer Debenhams in wake of the realisation that over half of their female customers wear a bra size DD or higher.
The shop asked 1,000 customers, both male and female - all of whom were shopping in their fuller-bust lingerie range, Gorgeous - which famous female they thought had the best cleavage.
"If you've got it flaunt it, but reveal your assets appropriately," the Daily Mail quoted Sharon Webb, Head of Lingerie Buying and Design for Debenhams as saying.
"It's no surprise that Marilyn was voted number one; she clearly wore well fitting bras and never made a boob of herself; she knew how much decolletage to bear.
"For most women, there is nothing that says fashion disaster like a bra that doesn't fit properly and if you're blessed with a fuller chest and not so keen on the beach ball bust trend, then this can be a challenge," she said.
