Kiernan Shipka Shows Off Her Fit Physique In A Teeny Tiny Red Bikini

Kiernan Shipka stunned her fans on social media with a sexy update!

The 25-year-old actress took to her Instagram Stories and posted a jaw-dropping photo. Kieran rocked a skimpy bikini that showcased her killer curves as she posed for a selfie.

Kiernan is no stranger to working for the camera in front of a photographer, but this time, she took matters into her own hands by taking the snapshot herself. She appeared to be ready for a day on the beach when she struck a sultry pose inside the living room. The area was near the terrace, and plenty of sunlight entered the place through the sliding glass doors -- making it conducive for indoor photography.

The "Chilling Adventures of Sabrina" star held her phone using her left hand and angled it in front of her shoulder to ensure that she captured the perfect angle. She left her right arm hanging down her side while popping her hip, which emphasized her curves. Kiernan looked straight into the looking glass as she took the selfie.

The background of the image showcased some furniture, such as a round table filled with various things, a cushioned square chair in beige, and a rug that matched. The balcony, which was surrounded by lush greenery, offered marvelous views of the ocean. Although, all eyes seemed to focus only on Kiernan and her bold swimwear.

Kiernan rocked a scanty red two-piece that popped against her fair skin. It included a top with triangle cups that were fully lined. The wide gap in the center displayed her décolletage, while its bottom band wrapped tightly around her ribs to keep the piece in place.

She teamed the upper garment with matching bottoms. It featured a waistband made up of strings that clung high above her hips. The front side of the piece sat low on her lower body, leaving her flat tummy entirely in view. In addition, the high leg cuts displayed her flawless bikini area.

Kiernan parted her blond locks in the center and let the strands fall over her shoulders. She added a little bling to her revealing look, including a gold necklace with a round pendant and a pair of sunglasses.

On another occasion, Kiernan took another picture of herself wearing a different set of swimwear -- a plaid, black-and-white number. It included a top with a low neckline and strings tied into dainty bows over her shoulders. The lower half of her bikini sat several inches below her navel and featured the same straps as the top.

Kiernan tied her hair in a bun with her long side bangs framing her face.

The "Mad Men" alum has maintained her insanely toned physique by working out regularly.

Her trainer, Harley Pasternak (who's worked with Ariana Grande, Jessica Simpson, and Halle Berry), shared two videos of Kiernan's sweat session in April 2021. In the first clip, she did a Nordic hamstring curl, which Pasternak described as one of "the most challenging and intense isolated hamstring exercises you'll ever do."
