In the old days, it was not common nor was it deemed appropriate for a young woman to go out without a knitted sweater (nattrøje) on over her white sleeves. However, on Lyø, during either hard work or dancing, young women took off their knitted sweaters and let their white sleeves show. This was called "throwing oneself bare-armed." It was also done in Hedebo when working in the fields.

The lovely Lyø Dance Costume has several elements:

a. visible white sleeves.

b. expensive silk ribbons displaying a flower motif hung loosely down in front. They were not tied.

c. the red and yellow flowered silk scarf was tucked into the bodice.

d. white apron with embroidery in the belt area.
