Women in the Netherlands have been using saddles without a nose for over a hundred years. They are generally referred to as rok zadels (which translates to saddles for dresses) and are usually used with step-through Oma fiets. I remember my grandmother using one back in the 60's and my mother brought one over from the Netherlands to Canada in the 70's.
