The balls of Vienna have always been a way for anyone to be elegant for a night.
維也納舞會向來都是一種能讓任何人一夜變優雅的方法。

　　Vienna is the capital of Austria, and it was home to some of history's most famous composers such as Haydn, Brahms, and the Strauss family. With such amazing music on hand, it is no surprise that Vienna would put it to good use by hosting hundreds of elegant balls. _(1)_
　　The Viennese ball season, called Fasching, extends from New Year's Eve until the Christian holy days of Lent, which is usually in mid-February. Vienna's balls involve strict dress codes and formal dancing, both of which add to the elegance of the event. Dancing is the real purpose of a ball. _(2)_ Other popular dances include the tango and fox trot, which are more modern ballroom dances. _(3)_
　　For most balls, the attire is extremely formal. Women are all expected to wear full-length gowns, and it is recommended that they not wear narrow skirts as that can interfere with the dancing. _(4)_ White tie events are the strictest, requiring white bow ties, shirts and vests, and black jackets with tails, trousers, and shoes. _(5)_ Balls in Vienna are fun, but customs also make them very formal, and anyone who doesn't meet the dress code may be turned away. Once inside, however, it's time to dance the night away in style.

(A) Less formal events also exist where attendees can dance swing, salsa, or other modern dances.
(B) Black tie events have simpler dress codes, which consist of black bow ties, dinner jackets, trousers, and shoes, as well as a white shirt.
(C) In fact, there are at least 150 official balls each season, and that number swells to over 300 if unofficial events are counted.
(D) The most popular dance in Vienna is the waltz, and at all traditional balls people dance the waltz.
(E) Men typically dress in white or black ties, depending on the ball.

今夜舞通宵
維也納舞會向來都是一種能讓任何人一夜變優雅的方法。
　　維也納是奧地利的首都，它是歷史上一些極富盛名的作曲家之發源地，像是海頓、布拉姆斯和史特勞斯家族等。維也納擁有如此令人驚艷的音樂在手，它能夠善用這些音樂來舉辦數百場優雅的舞會，這一點也就不足為奇了。事實上，每一季至少會有一百五十場正式舞會，而假使非正式的舞會場合也算進去，這個數字將增加到三百多場。
　　維也納舞會季又稱『狂歡節』，從除夕夜延續到四旬齋基督教聖日，通常是在二月中旬。維也納舞會包含了嚴格的服裝規定以及正規的舞蹈，這兩樣條件皆為該場合增添了優雅風采。而跳舞才是整場舞會的主要目的。維也納最受歡迎的舞蹈便是華爾茲，且在所有傳統的舞會裡大家都跳華爾茲。其他熱門的舞蹈包括探戈與狐步，這些都是比較現代的國標舞。另外還有一些不太正式的舞會場合，在該場合中，與會者可以跳搖擺、騷莎或其他現代舞。
　　對大多數的舞會來說，服裝極度講究。所有女士都必須換上等身長的禮服，且建議不要穿著窄裙，因為那樣可能會阻礙到跳舞。男士則通常會繫上白色或黑色的領帶，端看舞會類型而定。白色領帶的場合最嚴格，必須穿著白色蝴蝶結、白襯衫和白背心，加上黑色燕尾外套、黑西裝褲及黑皮鞋。黑色領帶的場合服裝規定比較簡單，其中包括黑色蝴蝶結、黑色晚禮服、黑西裝褲、黑皮鞋以及白襯衫。維也納的舞會逸趣橫生，不過許多風俗慣例同時也讓這些舞會變得相當正式，且任何不符合服裝規定的人都可能會被拒於門外。然而，一旦踏入了舞會，這便是盛裝舞通宵的時候了。
