Given the question: Information: - A ball gown is the most formal female attire for social occasions (such as white tie). It is traditionally a full-skirted gown reaching the floor, made of luxurious fabric, delicately and exotically trimmed. Most versions are cut off the shoulder with decollete necklines. Such gowns are typically worn with a stole (a formal shawl in expensive fabric), cape or cloak in lieu of a coat, "good" (couture or vintage) jewellery and opera-length gloves. Standard accessories are dancing shoes and a clutch style evening bag. Where "state decorations" are to be worn, they are on a bow pinned to the chest, and married women wear a tiara if they have one. The ball gown shape has changed little since the mid-19th century. Although artificial fabrics are now sometimes used, the most common fabrics are satin, silk, taffeta and velvet with trimmings of lace, pearls, sequins, embroidery, ruffles and ruching. - Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum. The word usually refers to visible light, which is visible to the human eye and is responsible for the sense of sight. Visible light is usually defined as having wavelengths in the range of 400700 nanometres (nm), or 4.00 10 to 7.00 10m, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths). This wavelength means a frequency range of roughly 430750 terahertz (THz). - Proteins (or ) are large biomolecules, or macromolecules, consisting of one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific three-dimensional structure that determines its activity. - Taffeta ( / tft / ; archaically spelled taffety ) is a crisp , smooth , plain woven fabric made from silk or cuprammonium rayons . The word is Persian in origin and means '' twisted woven . '' It is considered to be a '' high - end '' fabric , suitable for use in ball gowns , wedding dresses , and interiors for curtains or wallcovering . It is also widely used in the manufacture of corsets and corsetry : it yields a more starched - like type of cloth that holds its shape better than many other fabrics . An extremely thin , crisp type of taffeta is called paper taffeta . There are two distinct types of silk taffeta : yarn - dyed and piece - dyed . Piece - dyed taffeta is often used in linings and is quite soft . Yarn - dyed taffeta is much stiffer and is often used in evening dresses . Shot silk taffeta was one of the most sought - after forms of Byzantine silk , and may have been the fabric known as purpura . - A textile or cloth is a flexible material consisting of a network of natural or artificial fibres (yarn or thread). Yarn is produced by spinning raw fibres of wool, flax, cotton, or other material to produce long strands. Textiles are formed by weaving, knitting, crocheting, knotting, or felting. - The silkworm is the larva or caterpillar of the domesticated silk moth, Bombyx mori (Latin: "silkworm of the mulberry tree"). It is an economically important insect, being a primary producer of silk. A silkworm's preferred food is white mulberry leaves, though they may eat other mulberry species and even osage orange. Domestic silk moths are closely dependent on humans for reproduction, as a result of millennia of selective breeding. Wild silk moths are different (having not been selectively bred) from their domestic cousins; they are not as commercially viable in the production of silk. - Fibroin is an insoluble protein present in silk created by spiders, the larvae of "Bombyx mori", other moth genera such as "Antheraea", "Cricula", "Samia" and "Gonometa", and numerous other insects. Silk in its raw state consists of two main proteins, sericin and fibroin, with a glue-like layer of sericin coating two singular filaments of fibroin called brins. The fibroin protein consists of layers of antiparallel beta sheets. Its primary structure mainly consists of the recurrent amino acid sequence (Gly-Ser-Gly-Ala-Gly-Ala). The high glycine (and, to a lesser extent, alanine) content allows for tight packing of the sheets, which contributes to silk's rigid structure and tensile strength. A combination of stiffness and toughness make it a material with applications in several areas, including biomedicine and textile manufacture. - A larva (plural "larvae" ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. - Fiber or fibre (from the Latin fibra) is a natural or synthetic substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene. - Sericulture, or silk farming, is the cultivation of silkworms to produce silk. Although there are several commercial species of silkworms, "Bombyx mori" (the caterpillar of the domesticated silk moth) is the most widely used and intensively studied silkworm. Silk was first produced in China as early as the Neolithic period. Sericulture has become an important cottage industry in countries such as Brazil, China, France, India, Italy, Japan, Korea, and Russia. Today, China and India are the two main producers, with more than 60% of the world's annual production. - In planar geometry, an angle is the figure formed by two rays, called the "sides" of the angle, sharing a common endpoint, called the "vertex" of the angle. Angles formed by two rays lie in a plane, but this plane does not have to be a Euclidean plane. Angles are also formed by the intersection of two planes in Euclidean and other spaces. These are called dihedral angles. Angles formed by the intersection of two curves in a plane are defined as the angle determined by the tangent rays at the point of intersection. Similar statements hold in space, for example, the spherical angle formed by two great circles on a sphere is the dihedral angle between the planes determined by the great circles. - Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm "Bombyx mori" reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors. - In sewing and dressmaking, a ruffle, frill, or furbelow is a strip of fabric, lace or ribbon tightly gathered or pleated on one edge and applied to a garment, bedding, or other textile as a form of trimming.
