I have seen many Highland dancers and drummers wear a sporran on the side and not in the front. A discussion on this can be found at http://www.xmarksthescot.com/forum/f...an-side-10657/

There are also modern kilts that have pockets built in if you do not want a belt pouch or sporran. Some of these now come in a variety of tartans in addition to the solid color utility style kilts. I know Freedom Kilts is one place that has a traditional looking kilts with pockets and I have seen a few others.
