I just visited an online store that gives detailed measurements of the clothes. I was amused that a 55cm skirt length counted as a mini skirt. "mini" used to be an abbreviation for "minimal", as short as possible.
What is as short as possible? The shortest skirt length that doesn't make a woman uncomfortable? Some are only comfortable in jeans. Or the shortest skirt length that doesn't attract everyone's attention? The shortest skirt length a woman is willing to wear? The shortest skirt length of any woman in town? The possible explanations depend on current fashion, environment and personality.
It was when I was a student. A young lady might want to borrow a mini skirt from me. After looking at the selection, she says: "They're all too short for me."
A skirt over 50 cm can hardly be called a mini skirt. Mini stops (or starts Mini) at 40 cm. For the elderly who consciously experienced the first half of the 70s: "Really Mini is 35".
Mini is sexy (often). Longer skirts can look just as sexy. Attractive is a happy, friendly woman who feels good and radiates joy. Even without a mini.
Someone actually found this website by searching "kürzester minirock". I tried it: it appeared on a well-known "search engine" in 673rd place. Admirable search patience!
Of course I was curious about the search results. Unfortunately, many are somewhere between vulgar and ordinary. One definition is pragmatic: real mini is the lower edge of the bottom. Should I measure the skirt length of my dolls?
