A while back someone posted the following. It pretty much expresses why I, as an American of Scottish descent wears the kilt:
" I wear the kilt to honor my forebears and (as a veteran) for all those whom have died wearing the kilt far away from home serving something greater than just themselves. I consider the kilt the physical embodiment of my family legacy. When I wear the kilt, it's as if my ancestors are walking along side me."
