The star just had one sentiment to share: “Grateful.”

Christie Brinkley runs on optimism and ocean breezes—sometimes with a splash of Prosecco. Or that’s how Instagram makes it seem, at least. Now the 68-year-old is posing while frolicking in the ocean waves in a baby blue one-piece bathing suit.

In her latest tropical snap, Brinkley’s swimsuit nearly matches the waves behind her with a sunhat hanging on her back. Ankle deep in shallow water, crystals of salty solution splash up around her as her head rears back in pure bliss. It’s a truly breathtaking shot, which she simply captioned: “Grateful.”

The supermodel’s fans and followers showered the photo with love and adoration. “‘Gorgeous and Grateful,’” one person commented. “Stunningggg you beauty love this colour on you 👙👙👙👙👙,” another added. “WoW just WoW. You are blessed 😍,” someone else wrote.

Brinkley didn’t reveal exactly what beach she’s on in the photo, but in another recent Instagram, she mentioned being at her home in Turks and Caicos, so it’s likely that she’s soaking up some sun there. The beach is very clearly a happy place for the mom of three (and who could blame her!).

In January, she shared some snaps from a sandy sunset bike ride—wearing blue to match her set of wheels. “Sunset bike and stroll 🌝,” she captioned the post. “PS if you don’t ride the bike it will rust. Same thing with your body! You’ve got to move it !” In another post from the same month, she posed on the shore, writing, “Seriously… It’s the #beachlife for me!”

And while Brinkley loves to adventure outdoors, she never forgets to protect her skin with sunscreen. “Protect your skin while enjoying your sweet happy life. Be sure to use SPF everyday,” she captioned a beach-wandering video on January 7. “I’m wearing SPF 50, a swimsuit with long-sleeved sun protection, and a hat!”

When she’s not admiring the sea, she’s often tending to her garden—which also comes with sun exposure. Her favorite SPF brand to wear during both activities is Supergoop. “Supergoop sunblock is my absolute favorite,” she told Coveteur last year. “So while I’m overdoing it [in the garden], I’m taking care of my skin and not getting burnt.”

Supergoop—a sunscreen line beloved by many—offers a diverse selection of SPFs, including their cult-favorite Unseen Sunscreen for an invisible finish, Glowscreen for a dewy finish, and Mattescreen for those with oily skin.
