Barbie is a fashion doll created by American businesswoman Ruth Handler, manufactured by American toy and entertainment company Mattel and introduced on March 9, 1959. The toy was based on the German Bild Lilli doll which Handler had purchased while in Europe. The figurehead of an eponymous brand that includes a range of fashion dolls and accessories, Barbie has been an important part of the toy fashion doll market for over six decades. Mattel has sold over a billion Barbie dolls, making it the company's largest and most profitable line. The brand has expanded into a multimedia franchise since 1984, including video games, animated films, television/web series, and a live-action film.

Barbie and her male counterpart, Ken, have been described as the two most popular dolls in the world. Mattel generates a large portion of Barbie's revenue through related merchandise —accessories, clothes, friends, and relatives of Barbie. Writing for Journal of Popular Culture in 1977, Don Richard Cox noted that Barbie has a significant impact on social values by conveying characteristics of female independence, and with her multitude of accessories, an idealized upscale lifestyle that can be shared with affluent friends.

A bomber is a military combat aircraft that utilizes air-to-ground weaponry to drop bombs, launch torpedoes, or deploy air-launched cruise missiles. Bombs were first dropped from an aircraft during the Italo-Turkish War, with the first major deployments coming in the First World War and Second World War by all major airforces, damaging cities, towns, and rural areas. The first bomber planes in history were the Italian Caproni Ca 30 and British Bristol T.B.8, both of 1913. Some bombers were decorated with nose art or victory markings.

There are two major classifications of bomber: strategic and tactical. Strategic bombing is done by heavy bombers primarily designed for long-range bombing missions against strategic targets to diminish the enemy's ability to wage war by limiting access to resources through crippling infrastructure, reducing industrial output, or inflicting massive civilian casualties to an extent deemed to force surrender. Tactical bombing is aimed at countering enemy military activity and in supporting offensive operations, and is typically assigned to smaller aircraft operating at shorter ranges, typically near the troops on the ground or against enemy shipping.

During WWII with engine power as a major limitation, combined with the desire for accuracy and other operational factors, bomber designs tended to be tailored to specific roles. Early in the Cold War however, bombers were the only means of carrying nuclear weapons to enemy targets, and held the role of deterrence. With the advent of guided air-to-air missiles, bombers needed to avoid interception. High-speed and high-altitude flying became a means of evading detection and attack. With the advent of ICBMs the role of the bomber was brought to a more tactical focus in close air support roles, and a focus on stealth technology for strategic bombers.

Denim is a sturdy cotton warp-faced textile in which the weft passes under two or more warp threads. This twill weave produces a diagonal ribbing that distinguishes it from cotton duck. Denim, as it is recognized today, was first produced in Nîmes, France.

Denim is available in a range of colors, but the most common denim is indigo denim in which the warp thread is dyed while the weft thread is left white. As a result of the warp-faced twill weaving, one side of the textile is dominated by the blue warp threads, and the other side is dominated by the white weft threads. Jeans fabricated from this cloth are thus predominantly white on the inside. Denim is used to create a wide variety of garments, accessories, and furniture.

A doll is a model typically of a human or humanoid character, often used as a toy for children. Dolls have also been used in traditional religious rituals throughout the world. Traditional dolls made of materials such as clay and wood are found in the Americas, Asia, Africa and Europe. The earliest documented dolls go back to the ancient civilizations of Egypt, Greece, and Rome. They have been made as crude, rudimentary playthings as well as elaborate art. Modern doll manufacturing has its roots in Germany, from the 15th century. With industrialization and new materials such as porcelain and plastic, dolls were increasingly mass-produced. During the 20th century, dolls became increasingly popular as collectibles.

The inch (symbol: in or ″) is a unit of length in the British Imperial and the United States customary systems of measurement. It is equal to ⁠1/36⁠ yard or ⁠1/12⁠ of a foot. Derived from the Roman uncia ("twelfth"), the word inch is also sometimes used to translate similar units in other measurement systems, usually understood as deriving from the width of the human thumb.

Standards for the exact length of an inch have varied in the past, but since the adoption of the international yard during the 1950s and 1960s the inch has been based on the metric system and defined as exactly 25.4 mm.

A jacket is a garment for the upper body, usually extending below the hips. A jacket typically has sleeves and fastens in the front or slightly on the side. A jacket is generally lighter, tighter-fitting, and less insulating than a coat, which is outerwear. Some jackets are fashionable, while others serve as protective clothing. Jackets without sleeves are vests.
