This outfit was inspired by the idea of wearing a chambray with a black pencil skirt, seen somewhere on the internets. However, if you have a dark gray/black chambray, you wear that instead. And you wear some summer-y black wedges before the cooler weather sets in. But you might also take them off to frolic a bit.
What I really like about this look is that it incorporates elements of professionalism (the pencil skirt and heels) and a more casual feel (the chambray). Paired together, they strike the perfect balance for a day at the office where a skirt feels appropriate, but you don't want to be too too fancy. And, of course, the all black (plus some dark gray) is chic...or tough...
Depending upon which vibe you're going for ;)
