That and the fact a kilt never goes out of style. In highschool I went to a "70's party" where we all dressed up and I borrowed some of my dad's old stuff he still had lying around. Sure those pants and that shirt/jacket held up nicely for 20 years or so, but good GOD I wouldnt be caught dead wearing that polyester stuff now

So although a kilt from 1970 would hold up, it'd still look good too
