A classy business outfit can be put together by simple pieces like a white pencil skirt and dark blue military style shirt when combined with polished accessories like leather high heels, a belt and a bag at the same color.
Love the polka dot top and cardigan. The color of the cardigan (burgundy?) is beautiful. I like the color of the pant but would want a straight or skinny fit work appropriate pant (think Limited's Exact Stretch Skinnies).
