No, LBD -- I didn't know it, either!
I agree with what Celia and Angie said. I'm influenced both by the quality of light (or lack of it) and by my mood. I wear bright hues (cobalt!) in summer that feel too strong for me (and my ambient light) in winter. Meanwhile, in winter, I do gravitate towards more neutrals...but I also choose lots more bright berry colours -- cranberry, raspberry, fuchsia -- hues I rarely reach for in summer.
In all seasons I adore ink and bright navy. I like black, but tend to wear it best in summer when I can also show some skin or wear it with white. Grey is more for winter (to my mind). Taupe I can wear in all seasons, but prefer in fall/ winter.
But an all neutral outfit too many days in a row in the winter will send me pulling my hair out. I ADORE bright winter coats -- red, for me (I never, ever want to be without a red winter coat in my wardrobe) and I would love an orchid raincoat.
I also love adding "light" in the form of white or off-white. Another neutral, I know. But it perks me up.
