I'm a WAHM and WAH for two years prior to DS's birth. I work in software in the NW, so even when I was in the office, the dress code was super casual, so my style hasn't changed too much. For a few year I went through a flowy dress phase (which I called my "new age frump" look, and I abandoned that because it just wasn't flattering to my busty, curvy figure. Aside from this phase, my look has been pretty constant throughout the years.
My style varies by the season, but generally consists of nice jeans, fitted t-shirts, cardigans, capris, and the occasional skirt. I love polar fleece and will splurge on a new one at Patagonia during their February sale every few years. For shoes, I am loyal to a few brands (Dansko, Naot, Chaco, Birks, and/or Keen) because comfort and quality is really important when it comes to my feet!
I'd like to wear more skirts (the kind that hit right at or right below the knee), but they're just not that practical for doing housework and chasing a preschooler.
Makeup-wise, I wear a bit every day: foundation, lipstick/gloss, blush, and a coat of mascara. My short hair requires styling, which is why I'm growing it out into something I can throw back if I don't feel like messing with it.
