Traditional  Tenues LEROS outfits are nowadays used for dances. Women on the Aegean islands wore traditional clothes because for them it was a sign of beauty in the village on the island where they lived. Moreover, for them, it meant appearance to impress others but also exhibition of feminine beauty.
To go further, I would say that traditional costumes are a basic tool so that we understand the man and the society where he lives. Indeed, on the Greek costume, one can “read its history”, its local rites, the structure and values of a society but also the social place and personality of the person who wears it.

Traditional Greek outfits through time. They already existed since the Neolithic era where they were made of linen and yarn. In ancient times, most women made their clothes and the richest women distinguished themselves with their transparent and redish linen tunics from the island of Amorgos, the Amoryinas. These tunics remind me of the red linen of India. From the 16th sc, foreign visitors to Greece began to describe the typical traditionalGreek  clothes.
What Greek women’s clothes have in common? It is noted that in the islands especially in the cyclades (central Aegean), the main common point is the white tunic, which was propagated in the DODEKANISOS (Eastern Aegean), in the northern Aegean islands and in the Sporades (near the town of Volos). Secondary commonalities were the short shirt with narrow sleeves, the long shirt with wide sleeves folded towards the shoulders, a small bust and a kind of apron contrasting with the white skirt reaching up to the calves. For example, see the costumes of the island of Evia below.
Accessories of the traditional Greek costume. The Greek woman has always worn jewelry above her costume: large gold necklaces from the 17th sc, towering brooches on her chest and staple belts. On the island of KARPATHOS,

we have the pleasure of admiring the Kolaΐnès: these golden pieces squarely sewn on a large necklace of fabric. I believe that the costumes of the women of Karpathos are today the most impressive because of their pretty colors (photos above right). 

Let’s talk about traditional men’s costumes too. Men’s clothes are much more sober than women’s, so we don’t talk about it so much. Around the middle of the 19th century, you can see a fashion; to wear black Western European pants. However, most Greeks keep the “vraka”, puffy pants at the thighs. They wore the shirt and tank top buttoned up in such a way that no clothing itemwas hidden. The wide belt of bandeau fabric around the waist is also a must.  They wore no accessories except chaemali, a lucky necklace sometimes put around their necks by their wives. 

Today, dance and traditional costumes. Men and women can be seen at the great religious festivals of August on the Greek islands. The celebrations take place in the squares of a town or village on an island and everyone can admire the Greek men and women who dance in their traditional clothes. Indeed, traditional clothing in Greece is synonymous with dance, joy and flirtation. It is a way for dancers to relive the time spent at village festivals.
