Alli Simpson Sizzles In A Black Strapless Swimsuit

Alli Simpson, the younger sister of musician Cody Simpson, celebrated being home for the holidays by rocking a stylish swimsuit.

While Americans are experiencing winter weather, it's currently summer in Alli and Cody's home country of Australia. On Saturday, Alli took to Instagram to reveal that she had returned to the Land Down Under's Gold Coast ahead of Christmas. She's been living in Los Angeles, where she's spent years pursuing her dream of working in the entertainment industry.

During her visit back home, Alli decided to take advantage of the warm weather by doing a little sunbathing. In a photo that the 21-year-old actress and musician shared with her 1.3 million Instagram followers, she was pictured wearing a black strapless bathing suit. The garment clung to Alli's curves, showcasing her hourglass figure. The swimsuit had high-cut leg openings that showed off her shapely hips and thighs. It also included a fun and funky detail that made it a bit more visually interesting -- three rectangular cutouts on the sides showed extra flashes of Alli's sun-kissed, glowing skin.

Alli protected her eyes from the bright sun by rocking a pair of aviator sunglasses with gold frames. For her beauty look, she sported a petal pink lip. Her white eyeshadow and light application of mascara were visible through the lenses of her shades.

Alli had her short fingernails painted white. Her sleek, blond hair was parted down the middle and pushed back behind her shoulders.

Alli was posing on the edge of a pool. She leaned back on her hands with her left knee bent and her heel resting on the pool's edge so that her toes dipped into the water. Her right leg was partially submerged in the pool. A bright pink inflatable tube behind her created a striking contrast against her dark swimsuit.

Over the course of a few hours, Alli's followers liked her steamy poolside photo over 10,000 times.

"Absolutely stunning and beautiful the prettiest girl I've seen all week," read one response to her post.

"So sexy, baby," wrote another fan.

"Okay what the body goals perfect," a third admirer remarked.

"You are so freaking hot and beautiful as ever," a fourth commenter gushed.

Alli has modeled, acted, and sang, but she also occasionally makes headlines for commenting on her brother Cody's relationship with Miley Cyrus. Alli hasn't revealed whether Cody and Miley will be joining the rest of the Simpson clan in Australia over the holidays, but she did tell Australia's The Morning Show that her and Cody's mother recently met Miley. Alli said that the American pop star earned her approval.
