To preserve the longevity and shape of the Ingrid medieval dress made of cotton, it should ideally only be aired outdoors in the shade. If washing is unavoidable, separate hand washing in lukewarm water with a mild detergent is recommended, without rubbing or wringing the fabric. The dress should not be tumble dried or dried in direct sunlight, but ideally dried flat and, if necessary, ironed with plenty of steam on a low heat setting.
