Japanese women surveyed on how short a skirt (or hot pants) they are willing to wear give some depressingly modest responses.
The ranking (number of responses in parentheses):
1. Above the knee (2632)
2. Half covering my thigh (2376)
3. Covering the top of my thigh (1455)
4. If it just covers my derrière… (1232)
5. “Just” knee length (946)
6. Below the knee (622)
7. Ankle length (417)
Male mini-skirt admirers can of course be thankful that most responses are somewhere above the knee.
