I could always mail it to you for your opinion.

The problem is that this sounds as if it may require more hem than the kilt could take. I'd say there is a half an inch which needs to be taken up at most, but I don't know if this is too little. It is a 24" length and the shortest I could go would be 23". 23 1/2 looks good.

Also, the person who shortened it hacked the bottom of the kilt.
