If you don't mind losing the logo in back, you can dye the kilt. I've used RIT dye on mine a couple of times, but now I just leave it faded since it's my every-day knock-around kilt.

Some people say that RIT isn't the best dye, so check around. I've also heard of someone coating the logo with wax before dying the kilt. I don't know if that would actually work, anc then you have to get rid of the wax.

Anyway, good luck and enjoy your kilt!
