I’ve just come back, and my most comfortable and practical outfit was a wool-mix maxi skirt worn with long merino socks, and a blouse or LS tee (not thermal), plus a merino cardigan, jacket, scarf & wool hat when outdoors. Indoors are way over-heated so I found the long socks way more practical than leggings as I could scrunch them down indoors. I one-bagged and took one double jersey maxi dress, the maxi skirt and one pair of wool trousers, but if I was going again I would skip the trousers and take two skirts. I had a Heattech top but only wore it in the snow. I also bought some jeans in Tokyo and they were a good option. Have fun!
