Is the J. Crew tee in the Finds one of your festive elements? I love the subtle metallic sheen!
It was a strange weather season over large portions of the country. I think I live further north than you do, but I found that I was wearing sleeveless shells and knit tops with cardis or unlined blazers --- no coats. Because I tend to run warm, I already have mostly lighter items in my closet.
Your earrings and pants sound like great choices, and you might take comfort remembering that Angie tends to choose one new "festive" outfit each season. Perhaps it makes sense to simply repeat what works!
Of course, next December might be frigid, but you might consider adding one festive blouse -- perhaps in a patterned georgette, or other lightweight fabric. It sounds like your jewelry has some sentimental value -- perhaps it might make you be happy (and look fab) to build a couple of outfits around these pieces.
Happy Holidays! We're having chicken tonight, (not french, and not 3 of them) in celebration of the 3rd day of Christmas!
