Skirt length is no trivial matter. The hemline and the length of this universally liked clothing requires quite a bit of deliberation. Afterall, the skirt is accepted as the best attire for women in even the most traditional and prestigious business places. Then there is the hemline index, linking economy to skirt length.
The so-called hemline theory which came up during the 1920s says "shorter the hemline, stronger the economy". This observation of the relation between hemlines of skirts and the economy is attributed to Wharton Business School Professor George Taylor. In short, this means that during good economic times many women could afford silk stockings and hence raised their skirt hemlines. When economic conditions got worse the hemlines were lowered because they could not afford silk stockings.
In a more ordinary scenario of our lives, the choice of the length of the skirt is more of a personal choice. You will be deciding on the skirt length according to many factors, other than personal choice - like the fashion of the times, culture, height, weight and shape of the person, personality, and comfort. If you are looking at short skirts one more important consideration comes into play - the shape and condition of your legs.
