I was looking at the Osprey Men at Arms Series “The Black Watch” and I see that all the kilts pictured are above the kneecap or right at the top of the knee. Now is this because their kilt is a military uniform and would I be period correct if I were to wear my kilt that high? I know not to wear my kilt below the knee, but just how high can you go before you would be accused of wearing a mini-skirt.
