Alexandra Daddario All Smiles In Tight Bikini On A Yacht

Alexandra Daddario was back in her bikini for this sun-drenched moment, and she made sure to flash her mega-watt smile for the camera. Showing off her stunning figure in a tight bikini in a photo reposted to a fan account on Instagram, the 38-year-old actress flaunted her jaw-dropping frame in a striped, nautical two-piece, choosing a swimwear look that matched her ocean setting and wowing everyone who saw the snap. Opting out of a too-revealing neckline as she highlighted her fit body, Alexandra smiled from the edge of a yacht while kneeling, delivering her signature low-key charm and quickly seeing the snap go viral.

Scroll for the photo. Cruising through blue ocean waters and with a large, tourist-filled boat in the backdrop, Alexandra sizzled as she flashed her rock-hard abs and toned legs while on her knees.

Going sporty-style in a scoop-neck bikini top in blue and white stripes, The White Lotus favorite flashed only a little cleavage as she drew the eye from her torso to her legs, also going skimpy with a cute pair of matching briefs. While the likes of Kim Kardashian and Jessica Simpson will opt for a deep, often fake golden tan, Daddario sticks to her trademark porcelain skin, showing it here as she wore shades and looked happy.

With damp hair, it's possible that Daddario may have been for a quick dip, however her skin was dry as she enjoyed her day out. The star often makes headlines for sharing snippets from her beachy vacations — while some come without a geotag, fans do know that Alexandra adores Hawaii.

2017 brought Alexandra in a beachy role as she starred in movie Baywatch, one continuing the adored '90s TV show. While the skimpy swimsuits brought out Alexandra's curves as she dashed around the beach, they also showed how much muscle she'd packed on, something the star has opened up about.

"I started working out with Patrick Murphy, this amazing trainer in Los Angeles. The weight training helped me feel stronger, especially in my back, which didn’t hurt as much. Women should look into it if they haven’t before," she told Muscle & Fitness. When prompted to share other ways in which she stays in shape, the Dior ambassador added: "I do a ton of yoga. I find it more than just physically beneficial, but also emotionally. It’s great to take an hour to just chill out, be away from your phone, and focus on positivity."

The above photo was shared to Alexandra's Instagram as part of her ambassador role for clothing brand Alo Yoga. Modeling a tight, sleeveless tennis dress in dark shades, Daddario sizzled in her leggy number, likely also earning herself some cash.
