Alexandra Daddario Is Bikini Twinning With Hot Sister By A Lake

Photos showed Daddario flaunting her toned waistline and ample assets, plus those killer legs. The White Lotus star and her sister were walking toward the camera while chatting away — a gorgeous lake setting with serene greenery added attractive touches as the sisters rocked mint-green and white swimwear.

Daddario went plunging in a printed bikini that drew attention to her cleavage, also going for a spaghetti strap finish and classic-cut briefs.

Walking barefoot, Daddario echoed her sister's vibes, with Catherine modeling the same two-tone prints via a one-piece swimsuit with asymmetric cut-outs.

A swipe brought in some action as the sisters were seen out on the water and braving a paddleboard session. In the caption, Daddario made sure to confirm that her post was a paid partnership with Aerie, also fronted by country singer Kelsea Ballerini and Olympic gymnast Aly Raisman.

Addressing her 23 million+ fans, Alexandra wrote:

"Things we learned today: paddle boarding is harder than it looks. At least we got to be twins for a day in matching @aerie suits 🌊 @catdaddario #AerieREAL #AeriePartner."

Alexandra has spoken out on her partnership with Aerie.

"I believe in being comfortable in our own skin, not putting pressure on ourselves or the way that we look and accepting ourselves as we are," the blue-eyed beauty told People. "I think it's so wonderful that Aerie is a brand that doesn't photoshop their models, and they promote just being yourself and being confident and comfortable in your own skin."

Daddario is signed to multiple brands. She's been a high-profile Dior face in recent years and also represents activewear label Alo Yoga, plus designer Michael Kors.

In her People feature, Daddario also stressed the importance of balance and 360 wellness.

"I believe in that in everything — even exercise and what you eat — being easy on yourself and going with how you feel. I think that's a really important message to send people," she added.
