Peta looked stunning in her ivory crochet dress with a gold ring in the center of her décolletage and a midriff cutout.

Her sun-kissed skin glowed with radiant color and she wore a designer handbag from Italian fashion brand Salar.

Peta and Maksim took their adorable son to their favorite restaurant Cocina del Mar, where they ate delicious food and enjoyed the breathtaking view.

Chmerkovskiy posted a snippet of their dreamy night out on his Instagram story, writing, “One of our absolute favorites in Cabo is @cocinadelmaresperanza where they always take extra care of Shai :)”

Maksim was referring to his son’s special accommodations, as Shai was coddled in multiple blankets and lounging in two chairs pushed together.

Peta took to her Instagram story and posted some sweet photos of Shai enjoying bread at the dinner table and wearing his spiffy Ralph Lauren outfit.

“In his new @ralphlauren outfit,” the proud mom gushed. “I’m definitely never buying expensive brands again because they just break too quickly or never get worn, AND you can get just as nice clothes from cheaper stores…BUT this set was too cute to resist.”
