Have you ever seen the Uniform Project?
Starting last May, Sheena Matheiken decided to wear one dress every day as an exercise in sustainable fashion. She had her friend design something she thought she could wear no matter what the weather — it's short-sleeved and can be worn both frontwards, backwards, or open as a tunic — then had seven of the dresses made.
She adds various accessories: tights, jewelry, scarves, sweaters, vests, whatever, to make the dress look different every day. See?
I mention it because Christy Goodwin's outfit includes this plaid shirt dress, a piece almost as versatile as Matheiken's dress. In this incarnation, Goodwin's wearing it as a shirt over a tee and jeans, but in the past she's worn it as a dress with tights.
At the time, I commented on her little flats, and Goodwin said she never wears heels: "They hurt too much and I'm too clumsy."
