We’re Greeking out over these stunning looks.

Gigi Hadid put a modern twist on Grecian style as she rocked a white cutout dress at older sister Alana Hadid’s 40th birthday on Saturday, celebrating with family and friends at the toga bash.

“My Grecian Goddess Dream 40th ????️????✨ I feel so blessed and loved and cherished surrounded by my friends and family from all over the world,” Alana — who is one of Gigi’s half-sisters from her father’s first marriage along with another sister, Marielle — captioned a celebratory Instagram post from the party.

In one photo, Alana, Gigi, 28, and Marielle, 42, pose next to a pool as they sport their best toga-inspired looks, with the supermodel wearing a drapey white creation from Sportmax’s fall 2023 collection.

Gigi’s three-quarter-sleeved dress featured cutouts at the hip and belly, tying off in three knots at the front and bottom.

Leonardo DiCaprio’s ex-flame paired her dress with nude ballet flats and a simple necklace, wearing her hair in a slicked-back style.

As for the birthday girl, she sported a shimmering mauve dress from Australian brand Bronx and Banco, with the holographic creation crisscrossing her bust and wrapping around her body, tying off with gold rings.

Alana paired the dress with gold winged sandals from Ancient Greek Sandals ($355) and a flower crown, while Marielle wore a metallic white one-shouldered dress and silver heels. Bella Hadid seemed to be missing from the festivities, which was sponsored by Martini & Rossi and LIFEWTR.

The party follows Gigi’s recent vacation to the Cayman Islands, where the mom of one was arrested for marijuana possession along with her friend Leah Nicole McCarthy.

The “Next in Fashion” host seemed unbothered by the incident, sharing a photo dump of sunny pics that she captioned, “All’s well that ends well.”

Luckily, her vacation snafu didn’t keep her from celebrating her sister’s big day. Happy birthday, Alana!
