One instant influence -- more of my wardrobe sits in my "year round" closet. Less will be stored between seasons. The Cat -- the weather in Vancouver is vastly different than the weather in southeastern Ontario. There, we had short, rainy, windy autumns; long, cold winters (from November to late April, the average low around -10 to -15C but often going down to -30C or colder with wind chill) and lots of snow, ice, and dirty slush on the streets. Spring in my former city is short and chilly and summer is hot and muggy -- it lasts for about 3.5 months. On paper, the temps look moderate but with the humidity, the "feel" of the air is often about 35 to 38C. We had a particularly hot summer this year.
Vancouver has one of the mildest climates in Canada but is also extremely rainy and grey in the winter. I can expect some, but not much, snow here. It often melts the same day it falls, or the next day. Spring is long, damp, but pleasant with glorious blossoms that last for months. Summers are slightly shorter than in Ontario and considerably less humid. It's typically very sunny in July and August. May is also a very good month with lots of sun. June is strangely less predictable and not as warm as in Ontario.
Max looks disgusted with his collar in this photo, but he's actually surprisingly blasé about it. He does not enjoy having it put on, but once it is there he barely seems to notice it. Since our landlady is a bird lover and our garden is full of finches and hummingbirds, it's a necessity. I think the real problem for birds is feral cats but I'm not taking chances.
Angie, I agree that Seattle is much grittier than Vancouver. Vancouver always feels almost washed clean to me (coming from grittier, older, Toronto) -- except for the downtown east side, that is. There's grit to spare in that area of town.
JAileen, I do think the west coast dresses differently from the east, for sure. There are overlaps, of course. As LisaP says, Vancouver is not particularly stylish but is a very active city so you see gear, gear, gear. Toronto is more stylish but without much flair, except for distinct pockets. There are some really great designers there, though, if you know where to look. Montreal is where the fashion fun is!
