Many of my clients have recently gone back to work in some capacity. As a working mom it is important to look professional and polished but not so fancy that you can't scoop up the kids and run them to their after school classes. This is a high low mix.

Equipment silk blouse (perfect cut and love the collar)
Madewell moto jacket(a classic at a fair price)
COS skirt (just sold out but will be back)
