I am going to change focus for a while. There is much left to say about Lithuania and the Baltic area, and i will return to it.
Research of Italian costume is quite challenging, as in many places in Italy, there has long been little interest in maintaining this part of their culture. Another factor is that the large cities of Italy have always been in the forefront of developing the latest fashion. Because the local folk costume is further in time from current memory than some other places, there is less material available.
Italy can be divided into 4 regions when it comes to folk costume. Northern, Central, South, and Sardinia.
The north is characterized by costumes that fall within the general Alpine culture. There are several linguistic minorities that inhabit this region, Franco-Provencal in Aosta, Tyrolean Austrians in Alto Adige, Ladins just to the east of them, Friuli [Furlan] in the northeast corner, and Slovenian in the valley of Resia. Many communities have tenaciously clung to their folk costume as a part of their identity. To the south is the wide and very fertile valley of the Po river, which has been so much in the center of the general development of European fashion and history that little distinctive peasant culture has developed or survived.
The center includes the hilly country from Tuscany to Molise. There are some notable costumes preserved in this area, including Pescocostanza with their beautiful lace, Assisi with its distinctive embroidery, Scanno whose costume is derived from the middle East, and others.
The south includes Basilicata, Puglia, Catania, Calabria and Sicily, with some very colorful and rich costumes. Some of the most impressive are those of the Arbereshe, the Albanian ethnic minority which have developed their own distinctive costumes.
Sardinia, however, is the jewel of folk costume in Italy, having easily as many variants of folk costume as the entire mainland combined. Sardinia is currently divided into 8 provinces, and i will be presenting a short overview of only a handful of costumes from each. I was forced to leave out much material.Here is a map of Sardinia, showing the provinces and the major cities. You will notice that each location has two labels, the one on top is in Italian, while the one underneath is in the Sardinian language.
