While browsing through H&M's new arrivals for a story—yes, it's is part of my job—I saw a sporty sweater that looked incredibly familiar. Then it hit me: none other than Kate Middleton has worn

a similar version before. And upon further digging, I found a photo of the late Princess Diana in the very same trend, too. Is that kismet or what?

Varsity sweaters are certainly nothing new, but H&M has a knack for translating trends into extremely affordable pieces that are widely accessible. So when I come across a royalty-approved trend at a $30 price point with a full stock of sizes ranging from small to XXL, I knew I had to share. Scroll down to see how Kate and Diana styled the preppy sweater trend and shop it for yourself.
