If you check out Kate's look, you'll notice two things: it's casual, but super sexy. Props to her off-the-shoulder top. It's slouchy, but not dowdy, because she's showing some skin via a sultry shoulder. It's an easy way to sexy-up your apparel just a tad. Printed, solid, '80s-inspired tees — it's all fair game, just wear with confidence and channel Kate's carefree vibe.
