Dorit Kemsley and Lisa Rinna are each others' best customers. The Real Housewives of Beverly Hills fashion designers' wardrobes include pieces from both Beverly Beach by Dorit and Lisa's QVC line. Dorit likes to mix the two brands: She's paired Lisa's staple duster cardigan sweater with Beverly Beach leggings and dressed up her own Beverly Beach bike shorts with Lisa's QVC sparkly blazer.

Naturally, swimsuit queen Lisa is all in on Beverly Beach bikinis. Lisa spent part of her lake getaway this weekend in a sun-shielding bucket hat and one of Dorit's tiny neon green bikinis. It channels her bright lime reunion dress! This particular Beverly Beach swimsuit is a new design from Dorit, named after the one and only RHOBH newcomer Denise Richards. There's only one size left in the $68 top, which goes with $58 string bikini bottoms.

Dorit was thrilled about it all, writing in an Instagram comment: "Gorgeous Lisa!!! Love you!!" 

Lisa wrote back: "I surely don't look like you in it miss body but I love all your suits." Dorit replied to Lisa, "YOU are my inspiration! You are MY #GOALS."

Aw! Lisa Rinna on vacation is both goals and a mood. She showed another "Swimsuit of the Day" with a $175 square neck one-piece by the London brand Hunza G, paired with a Gucci hat and sunglasses.

Stay tuned for Lisa's next "Swimsuit of the Day."
