This has become a "uniform" of sorts. Button-up (preferably plaid and/or flannel), skinnies, fun shoes (maybe boots or booties, or sometimes borrowed oxfords from a friend), and occasionally a scarf.
And a faux-leather jacket on top is practically perfection.
Sometimes I'm pretty predictable...
shirt: Old Navy
