Croatian people used to wear traditional clothes. Women wore dresses, and men wore shirts and pants. If they lived in a village, they usually wore white clothes made from rough fabrics.
They would decorate it with hand-made patterns, lace (Pag lace), or golden buttons (dukati). Women sometimes had complicated hair-dos.
It is interesting that a tie is a Croatian invention. In the past, Croatian soldiers wore their neck pieces tied in a special way. In some languages, tie is called kravat, kravatta, corbata. All those names come from the name Croatian.
Today, people wear modern clothes like anywhere else. They wear jeans, shirts, dresses, sneakers, boots and so on.
