The splendid Scottish folksinger Karine Polwart tweeted one day about witnessing a girl being told not to climb a tree because she was in a very nice skirt. Or maybe just in a nice skirt, it was some time ago, and either way, this little song fell happily out and has been sung a handful of times since.
There is a particularly British distinction, I think, betweem a skirt, a nice skirt, and a very nice skirt. And you can climb trees in any of them, so there.
“Polly,” by Talis Kimberley, a very modern song in a charmingly traditional style.
