If you need a quick rich mom getup, Margot Robbie's latest outfit is the only inspiration you need. Her sporty half-zip pullover proves that the right sweater and jeans outfit can make you appear instantly put together. We found a similar knit style on major sale on Amazon, and it channels the same preppy-luxe vibe. For a casual outing with friends in Paris, Robbie dressed like a French local in head-to-toe designer. She wore a black Chanel sweater, baggy jeans and pumps, along with an oversized Hermès tote bag that added an elevated twist.
