We didn't call Marco, but Rihanna, Hailey Bieber, and more celebrities indeed called Polo.

Within days of each other, the "Lift Me Up" singer and the Rhode founder were both spotted wearing red, white, and blue striped collared sweaters from the brand Loewe. Rihanna cropped hers and wore it with a pair of low-rise jeans (to show off her baby bump) and a Louis Vuitton clutch. Hailey also kept things loose on the bottom with some baggy jeans, but decided to grab a black leather jacket and accessories to coordinate.

Rihanna and Bieber's tops look like rugby shirts, which are made with thicker fabric, but other preppy polos are being yanked from the classrooms and taken to celebs' closets, too. Back in October, Gigi Hadid wore a sweater polo, and Elsa Hosk wore one in an Instagram post she shared in February.

And as evidenced by the stars, when paired with a bottom that might be an unexpected choice, the outfit totally shifts. For example, when paired with cargo pants, like Hadid, the look is no longer super preppy, it's bold. When paired with flowy trousers, it looks like you're vacationing on the Amalfi Coast. And probably, most relatable, when paired with your work pants, it looks professional.

We're about ready to move into spring, but we're also not over Rihanna and Bieber's look. That's why we found a mix of both. Keep scrolling and check out stripes, solids, and more polo shirts.

To rub elbows with Rihanna, Bieber, and the rest of the stars in the polo club, snap up this Treasure & Bond shirt that's $49. The pattern is similar to their Loewe tops, but sans the red stripes. The length is already a bit cropped, so you won't have to tuck it in like the "Kiss It Better" singer, but sizes do go up to an XL if you'd rather go for a more oversized fit.

This Wosalba Lapel Collared V-Neck Long Sleeve Polo Shirt from Amazon is a little more polished — it doesn't have stripes and is just solid with a bright white collar that definitely strikes the eye. It also resembles the tie-neck trend seen on Mindy Kaling and Kate Middleton in recent months. And if you have long nails, or buttons are just not your friends, there's also a zipper version, and a few short-sleeve variations.

For a polo that's a bit snugger to the body, try this Cotton Emporium Collar Pullover from Nordstrom Rack. The short sleeves won't add bulk under a jacket, and all options — black, pink, and striped — are under $30.
