To make sure you can always run and fight, consider these points in dress shopping:
* A long loose skirt allows a full stride and can be girded in the manner shown.
* A short stretchy skirt will work just fine without girding, but the flash risk is higher.
* A narrow skirt must have a slit accommodating your full stride, neither too long nor too short.
* Never wear stiff balloon skirts, tight pencil skirts, or anything else that could get you killed because you cared more about appearances than survival. For the same reason wear low heels or dress flats.
