I had the same issue when trying to choose from among my clans tartan variations. I ordered swatches and kept them around the house for a while looking them over, asking other's opinions, etc. and when I felt comfortable I made a choice that best suited me and the reasons for buying it.

One peice of advise I was given was to make the decision and accept it. then you stop worrying about it. Don't order the kilt yet. Then look at the tartans again after a few weeks of not thinking about it and if you haven't felt that the desicion was wrong then go with the first choice. Once worry is removed things become clearer.

All the best,
Hugh
