This is from Call the Midwife, a British period drama. Is this a bicycle gang of nurses? That would be even awesome.
Some skirts are better for cycling in than others. Which is to say, heavier and stiffer skirts are better than light and frothy ones. But if you live in a city and you cycle to work and you want to wear something nicer than denim or corduroy, this might be helpful: a coin that latches in to your skirt to weigh it down.
There are some women who would like you to know how to ride a bicycle in a light and frothy skirt without having, ah, certain exposure issues.
In short, you rubber-band a penny into the hem of the front of the skirt. The slight extra weight in the skirt keeps it Add Mediadown between your knees.
HT to everyone who sent me this.
