Casual, very casual. Very suburban, but not RL or Soccer mom.
At home it's jeans/shorts and tshirts. Plain tshirts even as I have very few graphic type shirts that I wear out.
At work it's casual slacks (as close to docker/jean type of pants as I can find that don't need ironing), and tshirt type pullover shirts with a few casual tops thrown in.
If I need to dress up I prefer, skirts to dresses, and flats to pumps.
I'm a big fan of basic seperates that can be mixed and matched.
I don't wear a lot of button up type shirts....not sure why as I'm only average in chest size but I dislike button up shirts.
I only own slacks in tan/browns/kahki, black/gray, non work pants it's deniem and khaki (although I broke out this year and bought two pairs of (not loud) plaid shorts but I'll only wear them with solid colored shirts

). For tops I stick primary colors with only a few variations. I do have a couple of pink tshirts and one orange tshirt. I'm not very color brave.
I shop at Penneys, Lane Bryant, Ralph Lauren (even though I'm not RL type style), Cato, Target,
Walmart sometimes but mostly socks/bras and tshirts, Macy's/Dillards, Gordmans, I buy occasional pieces at some of the high end stores but if I pay that much I tend to stick to classic pieces in basic colors that will last through multiple seasons. Common stuff I buy midrange price, trendy pieces when I buy them are from walmart/target/cheapest place I can find them.
