The National Costume Center of Finland is dedicated to preserves national costumes and related materials from Finnish-speaking territories. The collection also covers costumes previously considered national costumes that continue to be worn as such today, as well as local and provincial costumes. 

The exhibition presents a traditional but today somewhat mysterious professional group, milliners. The professional title of milliner comes from the French word modiste. It means a designer, manufacturer and seller of fashionable accessories for women, especially hats. Milliner and hatter have traditionally been two different professions; milliners design and makes hats for women and hatters for men.
