Why it works: The floaty silk top in pastels is anchored by the navy trousers. The off white shoes are a little bit fun, and the (large) ring's colors compliment the top perfectly and lend some weight to the outfit.
What it needs: Just a little smile might make this a happier look...
Dress it up: Swap slacks for pencil skirt and switch peep toes to pumps.
Dress it down: Swap slacks for jeans, switch peep toes to flats.
