I'm afraid that if it's a traditionally made kilt that the pleats will have been cut to decrease the bulk made at the waist which would be a serious chore to fix. I'm not expert but I think that if it could be done it would be a real "trial". On a high note.. so what if it falls to the left!? I mean.. someone who knows might point it out but if the rig looks nice and the price is right... I wish you luck mate
