With all the snow we have been getting lately, I have been out skiing quite a bit. Cross-country skiing is one of my favourite winter activities. Below are a few images for some skiing outfit inspiration (the first is from the early 1920s, the second two are circa 1910). I love the idea of skiing in knickers. It seems like it would provide a lot of freedom of movement, but with the right socks would still be quite warm.
I've never heard of the above sport before, but it looks both very fun and very dangerous! The video below contains a short clip of people doing something very similar, behind both horses and a car (around 2:50). I love the skating outfit the girl has one at the beginning too.
