In this day and age, one would think the last thing a lady needs to worry about is being judged by the cross of her legs. That said, the way you sit can say a lot about you.
We all know that when wearing a skirt, we should keep it classy and avoid anything that could be remotely compared to that Sharon Stone-in-a-white-dress-move from “Basic Instinct.” Even crossing at the knees however can prove too revealing, for example, in the thigh area, depending on the length of the skirt.
The safest stance in the leg-crossing arsenal, for any occasion and any outfit is to either move both feet to the side, knees closed, with both heels on the ground or with heels crossed. The most important thing to remember here is to keep your knees closed part, otherwise you may end up revealing a little too much about yourself.
Some things are better left a mystery.
