When wearing a short skirt, a woman should choose clothing and accessories that complement the skirt and avoid tugging it down when she sits. She should choose a skirt that she feels comfortable and confident wearing.
A skirt focuses attention on the woman's lower body, so her other clothing choices should do the same. Since the wrists are often near the waist, a bracelet is a good accessory choice, as it draws eyes downwards. She should wear sandals or heels, as both make the legs appear longer.
When a woman pulls her skirt down when she sits, it appears that she is worried about how she looks. By not paying attention to it, she appears more confident.
