Joel Silver's annual Memorial Day party was held at Malibu beach, California on Monday, so Diane Kruger and January Jones arrived at the event wearing their most comfortable and chic ensembles.

Following her stint at Cannes where she wore unlimited glamorous dresses, it was refreshing to see Diane donning a laidback, beach get-up.

She wore a simple and plain baby blue sleeveless cropped top showing off her toned stomach and a matching pair of high-waisted culottes by 3x1.

The 38-year-old star stood tall in a pair of nude sandals with chunky heels and carried along a beige tweed blazer to keep her warm in the windy location.

She accessorized with a straw fedora hat with stripes details, then protected her eyes from the sun with a pair of plastic-framed sunglasses. Her hoop earrings added a fun touch to her overall look.

Joshua Jackson's longtime girlfriend barely wore any makeup and tied her blonde locks into a low ponytail.

Diane did not forget the whole purpose of the event and paid homage to the men and women of the military who served the country.

She posted a picture of a military cemetery on her Instagram and wrote: "Remembering all the brave men and women who gave their lives for our freedom and safety..Thank you."

January also donned a matching ensemble. She wore a white knitted sweater and a pair of '70s-inspired, distressed, flared jeans.

The 37-year-old Mad Men star accessorized with a brown cross-over bag and a pair of sunglasses. She wore barely-there makeup that completed her simple yet chic look.

Bella Thorne stole the spotlight when she arrived in a white maxi dress with cut-outs on the sides that flaunted her toned body.

The 17-year-old was later spotted changing into her bikini and enjoyed the beach.

Stars like Chris Martin, Toby Maguire, Courteney Cox and Kate Hudson also attended the annual event.
