I'm a capsule wardrobe person, and not a season switcher at all, because well, I don't have much clothes so everything fits in my wardrobe anyway.
My style is naturally dictated by the fact that I cycle everywhere I go, so long dresses, wide trousers, handbags, long heavy coats are just not possible for me.
My style is quite parisian (being a parisian myself). Loads of oversized tops, mostly shirts or plain tee-shirts. Quite unisex I'd say.
Just a handful of accessories (like statement earrings, head scarves and glasses) and a bit of make up (mostly red lipstick)
Very uncomplicated really.
My staple look is something like today - I cycled and went for lunch out + theater, a good 20 miles cycling day - oversized navy shirt, grey skinny jeans, black ankle boots, and an almost ridiculously oversized (I love oversized right) navy rain poncho.
I don't buy often, so far this year I bought: A white cotton top, a pair of white trainers (after my dog pooped on my previous pair), and the rain poncho. I have my eyes on a cashmere dark green jumper for the winter so that might be my last purchase of 2021.
I tend to apply the "one in, one out" policy.
For me it came naturally, because of the cycling situation, and my taste for minimalism. I identified years ago the style I liked, and I clung to it so far. I guess also the fact that I'm in my early 40s and that my weight has never changed since my early 20s makes it easier.
Regarding Macro vs micro trends, my theory is that macro trends involves the whole silhouette (like midi skirts, wide trousers, mom jeans and YES, oversized tops) whereas micro trends are item (or a piece of an item) based (one shoulder top, specific pattern or colours, bell bottom trousers).
For example, two years ago, plenty of women were wearing a plain white t-shirt with a kinda midi leopard skirt and white trainers. The silhouette stays, but the leopard skirt isn't as common now.
