Absolutely wear what you want, but do it with respect, and pride naturally. Everyone else here has already said that, and I cannot help but echo that.

Also, if you are looking to diversify your wardrobe... and are getting tailored kilts, I would suggest a look at a number of the district tartans... many of them are just stunning patterns, and some of them quite old too. National tartans are typically eye catching too. There are a LOT of options out there when it comes to choosing tartans... often I find, the hardest part is trying to make up your mind!
Good times!
