You don't know how important an item is..... until you're suddenly without it!
Glad you got your beautiful scarf back, Suz! It looks like delicious cranberry dessert. It does a magical job of transitioning your cool-toned blues, greys, silvers and whites into Autumn. What about your blue reds? Do they count as "cranberry", or do you only wear those in Dec?
To answer your questions:
I don't struggle with feeling "seasonally right". Spring and Summer colours are my faves, and I simply wear them year round in seasonally appropriate fabrics and silhouettes!
That said, I've carefully added toffee, whiskey and dark brown to my wardrobe over the last 4 years - and it makes everything feel more autumnal and wintery RIGHT AWAY. Yet, I wear those earthy browns with white and blue in the Spring and Summer too. Sorted!
My magical items that solve most problems: white pearls and light blue or red specs
p.s. Maybe you need to embellish your scarf capsule, Suz.
