toga（n.）
源于拉丁语“toga”，意为“斗篷或披风”，起源于“*tog-a-”原型，是“*(s)teg-”词根的带缀形式。罗马平民的外衣。
The toga as the Roman national dress was allowed to be worn by free citizens only. A stranger not in full possession of the rights of a Roman citizen could not venture to appear in it. Even banished Romans were in imperial times precluded from wearing it. The appearance in public in a foreign dress was considered as contempt of the majesty of the Roman people. Even boys appeared in the toga, called, owing to the purple edge attached to it (a custom adopted from the Etruscans) toga praetexta. On completing his sixteenth, afterward his fifteenth, year (tirocinium fori), the boy exchanged the toga praetexta for the toga virilis, pura, or libera—a white cloak without the purple edge. Roman ladies (for these also wore the toga) abandoned the purple edge on being married. [Guhl & Koner, "The Life of the Greeks and Romans," transl. Francis Hueffer, 1876]
作为罗马国家服装的长袍只允许自由公民穿着。没有完全享有罗马公民权利的外国人不能穿着长袍出现。即使是被放逐的罗马人在帝国时代也被禁止穿着长袍。在公共场合穿着外国服装被视为藐视罗马人民的威严。即使男孩子们也穿着长袍，因为上面有紫色的边缘（这是从伊特鲁里亚人那里采用的风俗)，称为“toga praetexta”。在16岁之前，后来是15岁时(“tirocinium fori”),男孩子们会把紫甲边的长袍换成白色的、没有紫边的toga virilis，pura或libera。罗马女性(因为她们也穿着长袍)在结婚后放弃紫色的边缘。【盖尔和小内尔，《希腊和罗马人的生活》，弗朗西斯·胡费尔译，1876】
裤子这种穿着方式(拉丁语bracae)是异国人波斯人，德国人和高卢人的穿着方式，并不是罗马人的穿着方式。因此，在罗马地理上，“bracatus穿着长裤”指的是“阿尔卑斯山以北”的地区。学院里的兄弟会，toga party自电影《动物屋》(1978)重新流行，但这部电影的背景设置在1962年，这种习俗似乎至少可以追溯到1950年代中期。
Down on Prospect Street, Campus Club held a toga party, at which everyone wore togas. Charter held a come-as-you-are party, at which everyone wore what they happened to have on, and Cloister held a party called "A Night in Tahiti," at which we'd hate to guess what everyone wore. The borough police reported that only one false alarm was turned in. [Princeton Alumni Weekly, March 19, 1954]
在普罗斯佩克特街，校园俱乐部举办了一个长袍晚会，每个人都穿着长袍。图鉴举办了一个“穿着一切随便来”的派对，每个人都穿着他们恰巧穿的衣服，修道院举办了一个名为“夜晚在塔希提”的派对，我们不敢猜每个人都穿着什么。自治市警察报告说只有一个误报。【普林斯顿校友周刊，1954年3月19日】
