With only one kilt how often could I get away with wearing it? Every other day? Once a week? The kilt would be a casual, daily wear kilt, not a dress kilt, and I don't work in an office or anything.

And how often should it be cleaned? I know that you can simply spot wash it (I couln't find this process explained anywhere) after each use, but as a rule of thumb how often should a kilt be cleaned?
