One of my clients, upon finding out I was a games athlete, told me she her parents were from Scotland, and her grandparents still lived there.

She said at her brother's wedding, her father (born in Scotland) was the only person not wearing a kilt... in his words he had to wear one in school and he'd never wear "that itchy thing" again. Her grandfather and uncles from Scotland wore them, as well as her American-born brother (who wore his dad's hand-me-down for the wedding).

Funny though, her family was from Glasgow and she's a late-20's/early-30's gal. I'm guessing her parents would have been in school no earlier than the late 50's through 60's. Were kilted schools common in the lowlands at that time?
