My updated work wardrobe, including some seasonal rotation, as below.
I have five dresses - two black, one purple floral, one blue floral (spring/summer), one pink/black floral (fall/winter).
Five bottoms - black pants, black capris (spring/summer), brown pants, grey skirt (fall/winter), black skirt (spring/summer).
Seven tops - teal knit long sleeve (really cold days only), mint green turtleneck (fall/winter), pink plaid long sleeve, teal sleeveless (spring/summer), brown elbow-length sleeve (fall/winter), blue/green short sleeve, teal print short sleeve.
Four sweaters - pink, blue, red (really cold days only), black/white print.
I don't use accessories because they irritate me, and have one pair of black work shoes, which I keep at work so they last longer and stay clean.
The system is pretty simple. I wear two dresses a week, Monday and Friday. For the rest of the week, I have all the bottoms in a row and all the tops in a row, and grab the first of each that match, plus a sweater if I need it. I tend to match up my clothes for the next week on Friday after I get home.
It's not perfectly matchy matchy like many capsules, but for that to happen I'd have to give up at least one of my favourite three colours of clothing - teal, blue, and bright pink.
