I don't know if we're a totally out kind of fashion culture anymore these days, to be honest, but I do think some things will be thought of as not trendy.
With the move to fluid fits I wonder if arty bagginess will go mainstream at all. I think that form fitting will be out, except for formal business wear and maybe for evening. Once we get to spring and the need for boots is lifted, I think fitted skinnies will be less prevalent.
I don't know if the metallic Birkenstock trend from last year will persist this summer or look old. And the other normcore esque shoes - Tevas etc. I do think that flat shoes in general will still be the dominant shoes. I almost never see anyone in heels anymore unless they're dressed up for an occasion, and heels plus jeans and blazer used to be a popular formula for work in my neck of the woods,
Marsala is the color of the year so I wonder if we'll get a few more dusty autumnal tones this year, maybe some orange.
ETA: and here's what the Washington Post thinks will be In and Out (not all fashion):
