Gaelic Ireland (Irish: Eire Ghaidhealach) was the Gaelic political and social order, and associated culture, that existed in Ireland from the prehistoric era until the early 17th century. Before the Norman invasion of 1169, Gaelic Ireland comprised the whole island. Thereafter, it comprised that part of the country not under foreign dominion at a given time. For most of its history, Gaelic Ireland was a "patchwork" hierarchy of territories ruled by a hierarchy of kings or chiefs, who were elected through tanistry.
Throughout the Middle Ages, the common clothing amongst the Gaelic Irish consisted of a brat (a woollen semi circular cloak) worn over a leine (a loose-fitting, long-sleeved tunic made of linen). For men the leine reached to their ankles but was hitched up by means of a crios (pronounced 'kriss') which was a type of woven belt. The leine was hitched up to knee level. (Gaelicattire.com) Women wore the leine at full length. Men sometimes wore tight-fitting trews (Gaelic triubhas) but otherwise went bare-legged. The brat was simply thrown over both shoulders or sometimes over only one. Occasionally the brat was fastened with a dealg (brooch), with men usually wearing the dealg at their shoulders and women at their chests. The ionar (a short, tight-fitting jacket) became popular later on. In Topographia Hibernica, written during the 1180s, Gerald de Barri wrote that the Irish commonly wore hoods at that time (perhaps forming part of the brat), while Edmund Spenser wrote in the 1580s that the brat was (in general) their main item of clothing. Gaelic clothing does not appear to have been influenced by outside styles. Women invariably grew their hair long and, as in other European cultures, this custom was also common among the men. It is said that the Gaelic Irish took great pride in their long hair--for example, a person could be forced to pay the heavy fine of two cows for shaving a man's head against his will. For women, very long hair was seen as a mark of beauty. Sometimes, wealthy men and women would braid their hair and fasten hollow golden balls to the braids. Another style that was popular among some medieval Gaelic men was the glib (short all over except for a long, thick lock of hair towards the front of the head). A band or ribbon around the forehead was the typical way of holding one's hair in place. For the wealthy, this band was often a thin and flexible band of burnished gold, silver or findruine. When the Anglo-Normans and the English colonized Ireland, hair length came to signify one's allegiance. Irishmen who cut their hair short were deemed to be forsaking their Irish heritage. Likewise, English colonists who grew their hair long at the back were deemed to be giving in to the Irish life. Gaelic men typically wore a beard and mustache, and it was often seen as dishonourable for a Gaelic man to have no facial hair. Beard styles varied - the long forked beard and the rectangular Mesopotamian-style beard were fashionable at times.

What other things did they wear?

Women wore the leine at full length.

Henry Havelock Ellis, known as Havelock Ellis (2 February 1859 - 8 July 1939), was an English physician, writer, progressive intellectual and social reformer who studied human sexuality. He co-authored the first medical textbook in English on homosexuality in 1897, and also published works on a variety of sexual practices and inclinations, as well as on transgender psychology. He is credited with introducing the notions of narcissism and autoeroticism, later adopted by psychoanalysis. Ellis was among the pioneering investigators of psychedelic drugs and the author of one of the first written reports to the public about an experience with mescaline, which he conducted on himself in 1896.
Ellis returned to England in April 1879. He had decided to take up the study of sex, and felt his first step must be to qualify as a physician. He studied at St Thomas's Hospital Medical School now part of King's College London, but never had a regular medical practice. His training was aided by a small legacy and also income earned from editing works in the Mermaid Series of lesser known Elizabethan and Jacobean drama. He joined The Fellowship of the New Life in 1883, meeting other social reformers Eleanor Marx, Edward Carpenter and George Bernard Shaw. The 1897 English translation of Ellis's book Sexual Inversion, co-authored with John Addington Symonds and originally published in German in 1896, was the first English medical textbook on homosexuality. It describes the sexual relations of homosexual males, including men with boys. Ellis wrote the first objective study of homosexuality, as he did not characterise it as a disease, immoral, or a crime. The work assumes that same-sex love transcended age taboos as well as gender taboos. In 1897 a bookseller was prosecuted for stocking Ellis's book. Although the term homosexual is attributed to Ellis, he wrote in 1897, "'Homosexual' is a barbarously hybrid word, and I claim no responsibility for it." Ellis may have developed psychological concepts of autoerotism and narcissism, both of which were later developed further by Sigmund Freud. Ellis's influence may have reached Radclyffe Hall, who would have been about 17 years old at the time Sexual Inversion was published. She later referred to herself as a sexual invert and wrote of female "sexual inverts" in Miss Ogilvy Finds Herself and The Well of Loneliness. When Ellis bowed out as the star witness in the trial of The Well of Loneliness on 14 May 1928, Norman Haire was set to replace him but no witnesses were called.

What year did he graduate?
never had a regular medical practice.
