Here are a couple pages I had ripped out of magazines (an ad & InStyle respectively) for inspiration.  I worked the looks with pieces I already had.

My takes:

For the sleek look:

I wore my skinnier  Nine West cargos with some chunky Franco Sarto heels, a grey Target tank and my flowy Nine West cardigan plus silver bangles.

For the feminine look:

Target peasant top, Target cargo pants, Earthies sandals, bangles.

For the dressed up look:

Nine West sequined tank, unknown sweater, Target cargos, Tahari heels

For the casual look:

Willi Smith cropped cargos, Walmart t-shirt, Gap jean jacket plus black flats
