I usually wear dress slacks and layered shirts at work (because I never know what temperature my classroom will be). On casual days I wear khakis or brown cords with casual layered tops. On casual days I wear either my chaco sandals or my rocketdog shoes with skulls and hearts on them, but the rest of the week I wear either heels or very practical black flat shoes. At home, I wear jeans and t-shirts with graphics on them.
My clothes are always pretty fitted but never tight. I do not wear revealing clothes. My skirts are knee-length at the shortest and I almost never show any kind of cleavage. If I reveal anything, it's my shoulders.
I don't wear make-up, and i rarely do anything to my hair aside from comb it and maybe pull it back. Sometimes I accessorize with a scarf and/or earrings, but I'm pretty low-maintenance aside from that.
I don't dress in a boring fashion, typically, but it's quirky in a quiet way.
Edit: Colors--I wear a lot of teal, green, blue, red, dark purpley pinks, brown, khaki, black
