You are so in-tune with your style that even a seasonal shift looks authentic. It’s not like - “new season, new me!” Your palette is a noticeable change, but still cohesive with your wardrobe.
I am with you on changing necklines and fit preferences. I only wear my crew neck tees under my knitwear now; every other top is v, turtleneck, or wide - like a deep boatneck or square. I find the shape more flattering on my upper body, although it can fight with my long neck and narrow face.
My own palette is moving away from greens (I already have so so much) and I am adding more warmer blues(petrol), teals, yellow, and various shades of brown.
