Information:  - India, officially the Republic of India ("Bhrat Gaarjya"), is a country in South Asia. It is the seventh-largest country by area, the second-most populous country (with over 1.2 billion people), and the most populous democracy in the world. It is bounded by the Indian Ocean on the south, the Arabian Sea on the southwest, and the Bay of Bengal on the southeast. It shares land borders with Pakistan to the west; China, Nepal, and Bhutan to the northeast; and Myanmar (Burma) and Bangladesh to the east. In the Indian Ocean, India is in the vicinity of Sri Lanka and the Maldives. India's Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia. Its capital is New Delhi; other metropolises include Mumbai, Kolkata, Chennai, Bangalore, Hyderabad and Ahmedabad.  - In fashion, midriff is a term for the human abdomen. The midriff is exposed when wearing a crop top or some forms of swimwear. The cholis worn by Indian women exposes a thin section of midriff, usually 3 to 4 inches.  - Satin is a weave that typically has a glossy surface and a dull back. The satin weave is characterized by four or more fill or weft yarns floating over a warp yarn or vice versa, four warp yarns floating over a single weft yarn. Floats are missed interfacings, where the warp yarn lies on top of the weft in a warp-faced satin and where the weft yarn lies on top of the warp yarns in weft-faced satins. These floats explain the even sheen, as unlike in other weaves, the light reflecting is not scattered as much by the fibres, which have fewer tucks. Satin is usually a warp-faced weaving technique in which warp yarns are "floated" over weft yarns, although there are also weft-faced satins. If a fabric is formed with a satin weave using filament fibres such as silk, nylon, or polyester, the corresponding fabric is termed a "satin", although some definitions insist that the fabric be made from silk. If the yarns used are short-staple yarns such as cotton, the fabric formed is considered a sateen.  - Fashion is a popular style or practice, especially in clothing, footwear, accessories, makeup, body, or furniture. Fashion is a distinctive and often constant trend in the style in which a person dresses. It is the prevailing styles in behaviour and the newest creations of textile designers. Because the more technical term "costume" is regularly linked to the term "fashion", the use of the former has been relegated to special senses like fancy dress or masquerade wear, while "fashion" generally means clothing, including the study of it. Although aspects of fashion can be feminine or masculine, some trends are androgynous.  - Lingerie are women's undergarments, and may imply their being fashionable and alluring.  - A crop top (also cropped top, belly shirt, half shirt, midriff shirt, midriff top, tummy top, short shirt, and cutoff shirt) is a top, the lower part of which is high enough to expose the waist, navel, or some of the midriff. The cropping of a top in this manner is generally limited to female garments. Bikinis and sports bras are generally not regarded as crop tops.  - A camisole is a sleeveless undergarment for women, normally extending to the waist. The camisole is usually made of satin, nylon, or cotton.  - Undergarments are items of clothing worn beneath outer clothes, usually in direct contact with the skin, although they may comprise more than a single layer. They serve to keep outer garments from being soiled or damaged by bodily excretions, to lessen the friction of outerwear against the skin, to shape the body, and to provide concealment or support for parts of it. In cold weather, long underwear is sometimes worn to provide additional warmth. Special types of undergarments have religious significance. Some items of clothing are designed as undergarments, while others, such as T-shirts and certain types of shorts, are appropriate both as undergarments and as outer clothing. If made of suitable material or textile, some undergarments can serve as nightwear or swimsuits, and some are intended for sexual attraction or visual appeal.  - The abdomen (less formally called the belly, stomach, tummy or midriff) constitutes the part of the body between the thorax (chest) and pelvis, in humans and in other vertebrates. The region occupied by the abdomen is termed the abdominal cavity. In arthropods it is the posterior tagma of the body; it follows the thorax or cephalothorax. The abdomen stretches from the thorax at the thoracic diaphragm to the pelvis at the pelvic brim. The pelvic brim stretches from the lumbosacral joint (the intervertebral disc between L5 and S1) to the pubic symphysis and is the edge of the pelvic inlet. The space above this inlet and under the thoracic diaphragm is termed the abdominal cavity. The boundary of the abdominal cavity is the abdominal wall in the front and the peritoneal surface at the rear.  - Nylon is a generic designation for a family of synthetic polymers, more specifically aliphatic or semi-aromatic polyamides. They can be melt-processed into fibers, films or shapes. The first example of nylon (nylon 6,6) was produced on February 28, 1935, by Wallace Carothers at DuPont's research facility at the DuPont Experimental Station. Nylon polymers have found significant commercial applications in fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging).<ref name="Materials/Polyamide"></ref>  - A bustier ( alternately bustiere ) is a form - fitting garment for women , which is traditionally worn as lingerie . Its primary purpose is to push up the bust by tightening against the upper midriff and forcing the breasts up , while gently shaping the waist . Nowadays , it might also be worn as a push - up bra under a low - backed dress , or as a camisole for outerwear . The bustier can also be worn as a half - slip under sheer upper garments if a bold display of the midriff is not desired . A bustier resembles a basque , but it is shorter . It reaches down only to the ribs or waist . Modern bustiers are often made with mesh panels rather than the traditional boning .  - A choli (Hindi Nepali: , , , "ravike" Tamil: , Telugu: (ravike), although choli is the preferred word Telugu Kannada: ) is a midriff-baring blouse or upper garment in the Indian sari costume worn in India, southern Nepal, Pakistan, Sri Lanka, Bangladesh, and other countries where the sari is worn. It is also part of the ghagra choli costume of India.   - Cotton is a soft, fluffy staple fiber that grows in a boll, or protective case, around the seeds of the cotton plants of the genus "Gossypium" in the family of "Malvaceae". The fiber is almost pure cellulose. Under natural conditions, the cotton bolls will tend to increase the dispersal of the seeds.
