National Cleavage Day is an annual celebration in South Africa.

It was started in 2002, and is held at the beginning of April every year. This year it falls on April 3 2009.

NCD has been sponsored by Wonderbra, Cosmopolitan and 5fm from Johannesburg. This year's events include a spoof "Vote for National Cleavage Day" campaign where "activists" photograph their own mock protests in support of NCD to win a vacation.

According to Wonderbra, National Cleavage Day is a celebration of women's independence and a reminder that they should be proud of their achievements and their appearance.

The day is intended to be cheeky and fun. Any money raised from bra sales and special events goes to The Sunflower Fund charity.

Many women support the National Day by displaying their cleavage and clothing retailers have joined in by supporting the associated charity.
