(Trying again, offline, since my previous attempt got eaten)
The very first thing I noticed, still at the airport, was my first ever pair of harem pants spotted in the wild. I think I saw about 10 pair in total during my trip.
What I did not see, anywhere except on a couple of store mannequins, was cropped flares. I don't know if that's because the transitional weather period was over, or if they just haven't penetrated yet. I did see everything else: shorts, jumpsuits, miniskirts, maxi dresses, and lots of jeans in every silhouette.
Everyone who warned me to bring two pairs of sneakers was right. They were ubiquitous, and very necessary. People walk everywhere: there is a constant surge of foot traffic at all hours. I saw a few ballet flats, sandals, a surprising number of wellies on the day it rained, but by far sneakers were in the majority. Worn with everything. I even saw white sneakers worn with black tights: semi-sheer with a denim mini, opaque with a black fit-and-flare dress.
Another item I noticed was dusters and long cardigans. They looked striking, billowing out behind a woman striding purposefully along. It made me wonder why I don't wear mine more often; then I realized, it's not the same effect when I'm standing around (often in white coat) or driving, and much of the walking in my life demands a coat with a closed front and pockets!
I saw hardly any hats, which surprised me. I guess sun awareness isn't really big yet. (I wore a white paper-straw fedora, which I thought looked sufficiently urban.)
I also hardly saw any grey hair on women. I can recall noticing 2, and one I couldn't be sure she hadn't dyed it grey to be trendy. I suppose my eye has adjusted, because when I first moved to my current region (20 years ago, and barely starting to turn grey), I was struck by how many relatively younger women were completely grey and very sharp looking (nice role models).
That's all I can recollect for now. I didn't do street style pics per se, but I could attach some crowd photos if there is interest.
