I am a woman. I ride my bike most places, weather permitting. Sometimes I wear dresses. I have, therefore, encountered the stubborn problem of accidentally exposing my upper thigh and undergarments when mounting, riding, and dismounting my bicycle.
Eager to see if this trick was as good as it seemed, I just tried it with a nickel and a hairband and took a spin around the office on my bike. The verdict: It totally worked.
