Things I generally don't do: pumps, flats, oxfords, heels over about 2-1/2", blazers/jackets, khaki or beige, white tees, black jeans, shorts, leggings (except occasionally under skirts), belts, florals, handbag collections, gold jewelry, "classic" pearls. Have sneakers for walking/sports only, not streetwear.
Must-haves: jeans, black and richly colored long and short sleeve tees for layering (no white), boots and bootlets, a variety of stylish walkable city shoes and sandals, tights, raingear jacket/windbreaker, zippered fleece tops, silver jewelry of all sorts.
Skirts and dresses must be knee-length or somewhat shorter, with a few maxis mainly for hot weather comfort. Also for summer: gauzy and/or sheer tops and shirts.
As for colors, gray is becoming my main neutral must-have, replacing
black--but I still love and wear black. (Have also brought on many browns
and purples, colors I didn't really wear until about 10 years ago.)
LBDs: I have several. But here on the west coast, I haven't had a lot of opportunity to wear them. That's OK; they're all vintage/thrifted and can stay in reserve until called on.
My trench coat is black and of not-so-classic cut, essential for any bad-weather professional meeting. (I have dispensed with the belt, epaulet thing and double-breastedness, all formulas that are tricky on a short-waisted, busty petite.)
I have some white button-ups, always have...oddly enough, used to wear some in high school that I LOVED. I'm bustier now and don't have to dress up for work, so I haven't worn them much lately. I can wear them far better than I can a white tee though!
