Well, it was trending hugely a few years ago and much less so now. But speaking for myself, I don't let that mess with my outdoor capsules.
The trend away from scarves has, I admit, altered I feel about my big scarves for indoor wear. I'm still wearing them (they'd become a real outfit maker for me, personally -- almost signature to my look) -- but I feel a bit meh about them in that situation, and am looking for alternate way to achieve the benefits I get from indoor scarves (pattern mix, colour near face, warm neck, outfit interest). There is a sense (for me) that it's a bit of a dated approach. Keep in mind that I've been wearing a ton of scarves for about a decade. So that affects what feels dated vs. what doesn't. If you jump on a trend early and wear it a lot, you are bound to tire of it eventually at least on a temporary basis. Unless it becomes true signature as with Katerina and as with blue and silver for my style.
However, when it comes to outdoor wear, if it works, wear it, baby!! Some current parkas come with a snug kind of dicky that makes scarves less necessary; see my Quartz one below that has a sort of inner jacket with high neck. Scarves are actually a pain with that coat. And unneeded even in the coldest temperatures.
But in coats without that feature, I personally find scarves or wraps to be quite useful and versatile, and they also help to stave off boredom when a person has to wear the same old puffer (or even puffers) for months and months on end.
