A cupless bra, sometimes known as a shelf, open tip, open nipple or open cup bra, is a brassiere design composed of a rigid, under-wired frame along the inframammary line, that supports or lifts a woman's breasts, without enclosing the breast in a bra cup.

A cupless bra is regarded as a topless garment, as the nipples and areolae are uncovered. The garment can be regarded as erotic and seductive negligee, which can accentuate an aspect of a woman's physical attractiveness by lifting and displaying her breasts. Variants of the cupless bra are cupless corsets, miniskirts, dresses or swimsuits. There is no set terminology, but an "open nipple" refers to a garment with a cut-out circle to expose the nipples, while a shelf bra is one that merely lifts the breasts.

A cupless bra may be worn under an outer garment to provide support or lift for the breasts, while giving the impression that a woman is braless, because her nipples may be evident even through the outer garment. Open nipple and open cup bras may be used by nursing mothers for breastfeeding. (see nursing bras)

Katrina Kaif (born 16 July 1984) is a British Indian actress and former model who appears in Indian films, mainly in the Hindi-language film industry. She has also appeared in Telugu and Malayalam films. She was voted the sexiest Asian woman in the world by Eastern Eye in the years 2008, 2009 and 2010. Being a British citizen, she works in India on an employment visa.

Kaif made her acting debut with Kaizad Gustad's box office bomb Boom (2003). She tasted success in 2007 with Vipul Shah's Namastey London and followed with such films as Anees Bazmee's Welcome (2007), Abbas-Mustan's Race (2008) and Kabir Khan's New York (2009). She has since appeared in critically and commercially successful films like Prakash Jha's political thriller Rajneeti (2010) and Zoya Akhtar's dramedy Zindagi Na Milegi Dobara (2011).

Kaif was born in Hong Kong, to an Indian Kashmiri father, Mohammed Kaif, and an English mother, Susanna Turquotte, both of whom are British citizens. Her parents divorced when she was very young. Kaif once stated, "My dad, unfortunately, and not out of choice, has had no influence on our upbringing, on our religious or social or moral bearings." When she came to India, she changed her surname to Kaif, because it was Indian in origin. Furthermore, Ayesha Shroff has maintained that the actress' original name is Katrina Turquotte. Kaif has seven siblings; a brother and six sisters. From Hong Kong, she and her family moved to China, then to Japan. From there she went to France when she was 8, and thereafter lived for a few months at a time in Switzerland, Poland, Germany, Belgium, and other European countries. Then she moved with her family to Hawaii, and eventually to her mother's home country of England. Although it is often assumed that Kaif is from London, she lived there only for three years before finally moving to Mumbai.
