Vintage Swedish navy women's shirts - these look like they've never been used. Maybe in the old days, Sweden wasn't so progressive in equal rights and women were not allowed to sail the seas.
The fabric consists mostly - if not entirely - of cotton, and the shiny brass buttons contrast it nicely. These very often come with a separate white collar that you can button on the shirt. This way you can just wash the collar a few times before washing the shirt itself. Wash at something like 60 degrees Celsius.
Sizes in the ladies' system, these aren't feelgood sizes. Lengthwise, these fit most women, and the sleeve cuffs can be buttoned up.
The condition overall is excellent. We would probably not lie much if we'd say these are mostly unused.
