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.
Like this look with denim shirt, Barrow Bologna chinos, IWC watch mod. Portuguese and knitted tie. I usually like aknitted tie with with a denim shirt. But not with chinos/khakis. I'd rather had this look without the tie
