Speaking as a photographer I can tell you camera position can have everything to do with apparent kilt length - and your height in a photo. Personally I prefer a kilt at the top of the knee and agree that a longer kilt seems "trollopy" for lack of a better word. Worse yet, like baggy shorts cut below the knee they tend to make you look shorter - and fatter. One last thought from me - if a traditional "high-waist" kilt is tailored correctly, it will not ride down with wear.
