I host a lot, and like you Lisa P, do all the cooking, decorating, serving and cleaning! I run around and need to be VERY comfy. Nothing tight. No fussy sleeves, no layers, no high heels, and nothing skimpy. Must feel warm too.
So for AT HOME 2019 holiday hosting this year - no jeans and no black. I'll wear velvet bottoms - pants and skirt - with an assortment of matched dressier pullover and footwear complements. (I have a soft pink, red and cream complement of top + shoes). Pile on the pearls, add nude hosiery, and that's it. Fits are tailored and gently fluid, which makes things look more polished. No slouch.
Here are the exact items, which I can mix and match as my mood desires. Velvet pants are not skinny on me. More straight cigarette. The items don't look great like this, but once they are in an outfit and finished, they look pulled together, and are just how I want to look for at home hosting. Relaxed, playful, festive, shiny, polished, grown-up, dressy, and free to move!
Going OUT and not hosting at home during the holidays is different attire.
