Ham,

Like yourself I've had very few comments. The most memorable was when I turned a rural corner and met a group of about 20 ramblers head on. As they passed one female walker exclaimed "Ooh! He's wearing a kilt" in a wolf-whistle-ish manner. :P
At the other end of the scale an elderly lady (on another occasion) remarked she was expecting me to be a lady as I was wearing a sk**t.
