Elizabeth Olsen dons chic retro swimsuit as she packs on the PDA with beau Robbie Arnett in Mexico

She starred in this year’s massive blockbuster Avengers: Infinity Wars.

But Elizabeth Olsen seemed keen on spending some time away from the silver screen as she enjoyed a romantic sunset stroll with boyfriend Robbie Arnett on the beach in Mexico.

The 29-year-old actress rocked a chic black-and-white swimsuit on the tropical retreat before cuddling up to her musician beau for a few sweet kisses underneath a thatched palapa umbrella.

Elizabeth looked flawless on the sand sporting a retro-inspired monochrome one-piece with a bias cut down her stomach.

The top portion of her cute suit featured black paneling leading to a seductive side cut-out and white bottoms.

She covered up her shoulders with a long white blouse left unbuttoned to reveal her golden tan.

Elizabeth was makeup-free for the ocean adventure and opted to accessorize with one solitary golden bracelet as her long, chestnut brown hair caught the wind.

Her boyfriend of nearly one year rocked a vibrant yellow tropical shirt with palm prints etched in grey ink in addition to a pair of black swim trunks.

The 25-year-old artist showed off a shaggy black beard to match his curly long hair on the relaxing retreat.
