Nothing like biting your tongue while a man in his 60s with modern frames and overweight is telling you that his WWII era costume is perfect. The old adage 'clothes maketh the man' is true to an extent but has limitations. He was of course dressed in a combat uniform of a frontline unit. He was also badmouthing early period reenactment as fantasy because of the lack of information that exists.
I don't care who reenacts, but if you're going to get superior about how wonderful your impression is, you personally better measure up.

I think what a wasted opportunity to spread some information and to help from those Scottish-reenactors. Surely they do the culture because they love it, so why not promote it?
It could be though that they laughed because they knew it was near impossible to get such items. I know people for example who've obtained tablet woven items for medieval purposes from weavers who've done limited runs. It is an unfortunate fact that many home crafts people get too old to do it and retire or they run out of interest and do something else, leaving those items they have created almost as rare as the originals.

A look at the suppliers linked to from this site over the years shows that many are no longer in business or no longer offer the same range.

That Fraser group in Canada that seems to have attracted lots of young people looks excellent. I'm a bit confused over whether it's a pipe band, reenactment group or if several groups are involved but they look great in their mid-18th century gear.
