As it happens, I bought a kilt off e-bay which turned out to be much shorter than I imagined. Great quality but too short. I felt I could wear it only in the house at first, but little by little, I have gotten accustomed to the freedom round the knees, as well as my own appearance in a mirror, and I now feel quite comfortable wearing the kilt out. I would not wear it to a
Scottish function where it would draw unwelcome attention, but in France where no-one knows any better, what does it matter?

I would not wear it in winter either.
The kilt is 50 cm long; perhaps not short enough to be called a mini?
