Spring's shirting MVP? The knit polo. It's the kind of piece that toes the line perfectly between casual and refined—easy to throw on, but elevated enough to look like you put in some effort. And right now, they're more affordable than ever. A bunch of our favorite brands have marked down their knit polos by up to 50%, with most ringing in under $100. That's a steal for something this versatile. Pair one with tailored trousers or faded jeans, toss on some loafers or sneakers, and you're set. It's the easiest way to look put together this spring without overthinking it. Just don't wait too long—deals this good tend to disappear fast. We've rounded up the best ones on sale right now, so you don't have to dig.
