And definitely opt for a tank, i.e., a full 8 yard, custom kilt, from one of the kiltmakers on this site. Rocky, Tweksberry, etc. make the best you can order. It'll outlast you and your children in all likelihood, and I just believe it's best to start out with a real, honest to goodness, full meal deal. You'll never regret owning a good custom kilt.
Or one of Matt's 4-yrd. box-pleated kilts...
