Question: Who mostly wore the overcoats popular in the Koryŏ period?

Context paragraphs:
Ed Marion: Ed Marion (1927 – 28 April 2008) was an American official in the National Football League.  Marion was in the league from 1960 to 1987 and officiated in Super Bowl V, IX and XI.  He wore the number 26 for the majority of his career (during the 1979–81 period, he wore number 6).

Greco-Roman hairstyle: In the earliest times the Greeks wore their hair "kome" (long), and thus they are constantly called in Homer "karekomoontes".  This ancient practice was preserved by the Spartans for many centuries.  The Spartan boys always had their hair cut quite short ("en chroi keirontes"); but as soon as they reached the age of puberty, they let it grow long.  They prided themselves upon their hair, calling it the cheapest of ornaments ("kosmon adapanotatos"), and before going to battle they combed and dressed it with especial care, in which act Leonidas and his followers were discovered by the Persian spy before the battle of Thermopylae.  It seems that both Spartan men and women tied their hair in a knot over the crown of the head.  At a later time the Spartans abandoned this ancient custom, and wore their hair short, and hence some writers erroneously attribute this practice to an earlier period.

Goryeo: Goryeo (고려 ; 高麗 ; ] ; 918–1392), also spelled as Koryŏ, was a Korean kingdom established in 918 by King Taejo.  This kingdom later gave name to the modern exonym "Korea".  It united the Later Three Kingdoms in 936 and ruled most of the Korean Peninsula until it was removed by the founder of the Joseon in 1392.  Goryeo expanded Korea's borders to present-day Wonsan in the northeast (936–943), the Yalu River (993) and finally almost the whole of the Korean Peninsula (1374).

Ayam (cap): An ayam is a Korean traditional winter cap mostly worn by women in the Joseon period (1392 – 1910) for protection against the cold.  It is also called aegeom which literally means "covering a forehead" in Korean.  There is a historical record which mentions that officials in a low class called "iseo" (이서, 吏胥 ) wore "ayam" in the early Joseon period, so it was a unisex cap.  However, it is not clear whether the shape at that time was identical to that of the later period.  During the late Joseon period, an "ayam" was usually worn by female commoners.  Especially in the western part of Korea, "kisaeng" (female Korean entertainers) commonly wore an "ayam", and they were also worn as a simple formal headgear.

Matsukura Katsuie: Matsukura Katsuie (松倉 勝家 , 1598 – August 28, 1638) was a Japanese daimyo of the early Edo period.  As the son of Matsukura Shigemasa, Katsuie was notorious for suppressing Catholics in his domain, setting high taxation and assigning intensive labour to its peasants, later causing the Shimabara Rebellion.  He was also renowned for dressing disobedient peasants in straw overcoats and then setting them on fire.

Shoulder pads (fashion): Shoulder pads are a type of fabric-covered padding used in men's and women's clothing to give the wearer the illusion of having broader and less sloping shoulders.  In men's styles, shoulder pads are often used in suits, jackets and overcoats, usually sewn at the top of the shoulder and fastened between the lining and the outer fabric layer.  In women's clothing, their inclusion depends by the fashion taste of the day.  Although from a non-fashion point of view they are generally for people with narrow or sloping shoulders, there are also quite a few cases in which shoulder pads will be necessary for a suit or blazer in order to compensate for certain fabrics' natural properties, most notably suede blazers, due to the weight of the material.  They were popular additions to clothing (particularly business clothing) during the 1940s, 1980s, and late 2000s/2010s.

Wakashū: Wakashū (Japanese: 若衆 , "young person", although never used for girls) is a historical Japanese term indicating an adolescent boy; more specifically, a boy between the ages at which his head was partially shaven ("maegami") (about 5–10 years of age), at which point a boy exited early childhood and could begin formal education, apprenticeship, or employment outside the home, and the "genpuku" coming of age ceremony (mid-teens through early 20s), which marked the transition to adulthood.  During this period, the "wakashū" wore a distinctive hairstyle, with a small shaved portion at the crown of the head and long forelocks at front and sides, and typically wore kimono with open sleeves ("wakiake"); boys from wealthier families could wear "furisode".  After the coming of age ceremony, the forelocks were shaved off, giving the adult male hairstyle ("chonmage"), and the boy assumed the adult male style of kimono with rounded sleeves.  Although any person would be clearly classified as a child, "wakashū" or adult, the timing of both boundaries of the "wakashū" period were relatively flexible, giving families and patrons the ability to accommodate the development and circumstances of the individual boy.

Derrick Evans: Derrick Errol Evans (born 15 November 1952), better known as "Mr. Motivator", is a Jamaican-born British fitness instructor.  He rose to fame in the early 1990s through appearances on the UK breakfast television show GMTV, where he performed live fitness sessions and offered tips and advice to viewers.  Mr Motivator would often perform these workout sessions live before Power Rangers would air as part of GMTV programming.  Mr Motivator mostly wore tight fitting and very colourful spandex outfits for his fitness sessions.  In response to the popularity of his fitness sessions, he released a number of fitness and workout videos in the 1990s.

Dopo (clothing): The dopo is a variety of "po", or overcoat in hanbok, which was mostly worn by male Confucian scholars called "seonbi" during the Goryeo and Joseon period.

Women's golf in Australia: While not being urged to avoid competition, women had few opportunities to compete in sport in Australia until the 1880s.  After that date, new sporting facilities were being built around the country and many new sport clubs were created.  One of the reasons women were encouraged to play croquet, tennis and golf during the late 1800s was because it was scene as beneficial to their health.  These sports were also seen as passive, non-aggressive and non-threatening to the period's concepts of masculinity and femininity.  During the late 1800s and early 1900s, women were allowed to be members of golf clubs but most women could not be because the game was too expensive to play.  Women were also limited because of restrictions imposed upon them by the men who ran the clubs and courses.  For example, at the Brisbane Golf Club in 1901, women were not allowed to become full members, only associate members, could not belong to any club committees and there were limited times when they could play.  Women were allowed to play and did in places such as Willowburn, Queensland.  Like other sports of the time, women wore long sleeved blouses and skirts that were ankle length.  They also wore hats while they were playing.
