National Cleavage Day (abbreviated NCD) is an annual celebration held in either March or April in South Africa, sponsored by the brassiere marketer Wonderbra. National Cleavage Day was started in 2002 and held at the beginning of April every year. Wonderbra together with Cosmopolitan magazine and 5fm, a SABC radio station mainly based in Johannesburg, sponsor the observation.
Anita Meiring, public relations consultant for Wonderbra, described the event: "It is a day for women to realise that their cleavage is something unique and that they should be proud of it." "It gives women a chance to be beautiful and glow in the furtive, yet appreciative, glances their cleavage evokes from men". She also explained, "It gives men a legitimate reason to stare at boobs."
Samantha Paterson, a brand manager for Wonderbra, said that National Cleavage Day was started as a way to solemnise women's independence and power in all facets of life, from their careers to their relationships to their own destiny. Paterson said the day is intended to be lighthearted amusement and that the revenue will be donated to the Sunflower Fund. The fund is a non-governmental and non-profit organisation based in Cape Town with a stated aim to help South African citizens diagnosed with leukaemia and other life-threatening blood diseases.
National Cleavage Day is celebrated at office premises, restaurants and bars throughout the nation. Most people polled on the streets during the celebrations in 2002 expressed positive view on this event. During the occasion of the National Cleavage Day in 2002, twenty local girls in Johannesburg and another twenty girls in Cape Town were called in for the purpose of distributing stickers and G-strings to selected female drivers. The celebration of the NCD in 2006 started early in the morning of 7 April when women showing their cleavages in Edgars, Foschini Group and Truworths at La Lucia Mall, Gateway Shopping Centre and the Pavilion handed out Cosmopolitan magazines free of cost to customers. A competition was organised at the Cafe Vacca Matta called the "Best Cleavage." Thousands of women in the province of KwaZulu-Natal displayed their cleavages in support of this event. Local manufacturers and retailers of undergarments have joined in support of the celebration of the NCD and it marks some new industry shifts.
