Every time I wear a suit-style skirt (just at or above the knee, more straight-style pencilish skirt), I have a problem wherein it rides up incessantly (sp?). the skirts fit well at the waist and hips and bum, but whether or not I'm wearing hosiery, as I walk, the skirt rides up to terrifying heights and becomes almost indecent. I like the clean lines and versatility of such skirts, and I reach for them often... but then almost always regret it by the time I get to the office.

So my questions are:
1) Am I just skirt-impared? Or does this happen to you, too?
2) How do I make it stop?!
