Every season has a signature pattern. Plaid is perfect for fall and winter, florals are undeniably springy, and gingham screams "summer." The playful print is popular on a wide variety of summer clothing and accessories like bags, dresses, shorts, and, as Reese Witherspoon just showcased, swimsuits. 

On June 29, The Morning Show star shared a photo on Instagram in which she's wearing an eye-catching one-piece swimsuit in a navy, royal blue, and white gingham pattern. She aptly captioned the carefree photo "If 'vacation' were a swimsuit," and we couldn't agree with her comparison more.

The cute one-piece is from Witherspoon's clothing brand Draper James' collaboration with Lands' End (hence the #ad in the caption), and it's also available in pink gingham and a kelly green floral print. The checkered pattern reminds us of cheerful picnic blankets and tablecloths for backyard barbecues — and when it's in bold colors on a slinky swimsuit like Witherspoon's, it's a true head-turner. 

At $115, the former Big Little Lies star's exact pick isn't cheap, but there are plenty of affordable gingham swimsuits out there to choose from, starting with this red and white one-piece and this green and white bikini, both of which are on sale at Old Navy for just $15 and $20, respectively.

Witherspoon isn't the only celeb who has recently turned to gingham: Earlier this month, Kate Middleton wore the print in the form of a red collared blouse while frosting cupcakes with her kids, and just a few days later, Blake Lively deviated from the typical white sneakers stars are often spotted in by wearing a pair of Nike Air Force 1 shoes in beige gingham.

From thick stripes to palm-leaf prints, Witherspoon never shies away from embracing cheerful patterns, but this particular look is one we're itching to copy this summer. Below, shop four more gingham swimsuits à la Reese Witherspoon from Amazon and Madewell.
