thanks a lot for your warm welcome and your helpful replys.
iīve naturally made the experience that each kilt is different. now with those made or adjusted from my mother (and these were the first i wore until i got some from scotland)i didnīt even mind about the topic. their under apron went down from itself, because they go only to the middle of my left knee. That was part of the fascinating things among the kilt, that i could move and sit like in a trouser without to have to touch anything on the garment.
i ve to add that with these kilts i made an other mistake too: stitching the pin threw both aprons. in this way the under apron hold with the outer one, it went down.
now when i got my geoffrey tailor kilt from ebay last week, and i saw the huge under apron, that was the beginning of making me thinking. i was worrying and thought it was for larger waists, but as i understand now from u it is the way they are made. in fact those needs the karate chop, but i would claim to achieve the same result without even touch the kilt while sitting down. (excepting the pleats) that belongs to the mystery of wearing kilt for me, because one could sit down, spread its legs, without any touch. is my method and aim so weird to you?
i already had my sessions in front of the mirror and came to the result, that for some kilts the way i discribed, was the best. some kilts, don t blame me, fulfill the sitting quest better, when both aprons are stitched together.

i m thinking about what to do with the tailormade kilt but as i know now from u guys, that this long aprons are the koscher way, i ll finally try this way.

the winter is for sure like in norway, and i absolutely need a really heavy kilt. my heaviest so far is maybe a 13 oz one. but i m doubting about the cold air coming from bottom... but if my body is well packed should work maybe?

i only have seen once a guy wearing the kilt in vienna, where i live and even in austria, and this was the day when we had highland games in vienna. the composer gustav mahler said, "if something happens, it happens with 20 years delay in vienna".
