EVERYONE IS WEARING a skirt. Some skirts are shorter than others. Shorter skirts are easier to see up, especially when climbing a ladder.
If you’re wearing a long skirt, you have to get all the way to the top of the ladder before people start seeing up your skirt, and even then it might require some searching through levels and layers of fabric, particularly if your skirt is not only long but also blousy.
If you’re wearing a short skirt, you don’t have to climb very far. In fact, the moment you step onto rung number one, everyone can see up your skirt.
