Why do girls pull up yoga pants?

Seems I notice girls yanking up their yoga pants , when I'm in a line up or at the gym... I thought it was because yoga pants drop over time , but they seem super elasticy, and I'm not convinced that wedgies are comfortable (kinda hot though)

Someone told me girls do this as a way to hit on guys..

Any women use this technique? If this is true , i might start hitting on these
