Kate Bosworth showed off a perfect cocktail-party look in an embellished Stella McCartney sheath while attending a Harvey Weinstein-hosted Oscar-week fête.

She smartly keeps the rest understated — take a cue from the look and keep your jewels minimal and makeup and hair easy and natural. Feeling inspired?
