For me, I think what made me interested was looking at an album that we've had for a good 20-25 years, at least. Was the Highland Pageantry album by RCA, which was a recording of one of the Black Watch pipe bands from Scotland. Also helped seeing Rob Roy and Braveheart... I bought a kilt back in '01, thinking I could shrink enough that it'd fit... Yeh, right. About a year later, I purchased my first properly-fitting kilt (the Lennox District kilt for $150). Since then, I've purchased two more trad. kilts, and am in the process of purchasing a used standard Khaki Original UK from a member over at Tom's... I went from being mainly a jeans/shorts wearer, to mainly kilts within the first month of having the Lennox kilt...
