Read the text below. For questions 1 - 6 choose the correct answer (A, B, C or D).

Most, if not all, countries have their traditional dress which people wear on certain occasions, especially national or religious holidays. The same goes for the English-speaking countries. Scotland and Wales certainly seem the best examples here. The Scottish and Welsh national costumes are often considered to be Britain's most well-known dress, though the Scottish ones are definitely more recognisable across the world. Most foreigners will have some idea what a typical Scotsman looks like!

The Scottish national dress is called the kilt and it symbolises Scotland alongside whisky and haggis. The kilt is made from a tartan material and each Scottish clan has their own unique pattern of the fabric. Some people believe that wearing a kilt in a tartan which does not belong to their family brings bad luck.

Kilts are worn only by gentlemen and are complemented by a shirt, a waistcoat, a tweed jacket, stockings, special shoes and a sporran (a small bag). Sometimes men also wear small hats called bonnets which show the clan's symbols. Women, on the other hand, wear tartan dresses or skirts and shawls (big scarves).

As for the Welsh national dress, it's women who wear the most characteristic costumes. A typical lady’s outfit is made up of a small white cap underneath a large black hat, a white blouse, a red flannel shawl, a long checked skirt and a white apron. In the past women always used to wear black woollen stockings and carry small baskets.

Although there has never been a traditional Welsh costume for men, now, as a result of recent Welsh nationalism, men have designed special tartan trousers or even kilts. As a matter of fact, the Welsh traditional clothes have survived mainly due to the efforts of Lady Llanover (a Welsh patriot) who realised that the Welsh national identity was disappearing because of English or European influences.
