Lookalikes: Ashley Graham, 31, stars alongside her little sister Abigail, 25, in her new Swimsuits For All campaign 

Ashley Graham struck a pose with her younger sister Abigail for a heartwarming Swimsuits For All campaign that was inspired by their childhood photos.

In honor of her latest limited-edition capsule collection with the brand, the 31-year-old model stars alongside Abigail, 25, in her ‘Growing Up Graham’ campaign, which is a celebration of sisterhood.

As part of the playful beachside shoot in Punta Cana, the two siblings recreated pictures from their childhood — all while modeling Ashley’s sizzling swimsuit designs.

Sexy look: Ashley proudly showed off her famous hourglass curves in a leopard print monokini featuring a layer of black netting

Retailing for under $104 per swimsuit, the nine-piece Ashley Graham x Swimsuits For All Summer 2019 collection features mesh panels, see-through netting, exotic florals, and animal prints.

While on set, Ashley proudly showed off her famous hourglass curves in a leopard print monokini featuring a layer of black netting.

She posed on the beach and in the surf as famed photographer Ben Watts captured her solo shots as well as images of her with her sister.

The Nebraska native also donned the racy monokini while posing alongside Abigail, who was modeling Ashley’s new one-shoulder one-piece swimsuit that is topped with a taupe mesh overlay.

‘Abigail has always been my rock, and I was honored to have her by my side during this photoshoot,’ she said. ‘Plus, she’s a new mom and has never looked hotter in a swimsuit!’

Ashley also paid tribute to her sister on Instagram on Tuesday while sharing a behind-the-scenes video from their shoot.

‘Couldn’t be more excited to have my stunning sister @abigailgrahamralston by my side in my new @swimsuitsforall campaign,’ she wrote.

‘Abby, we have been through it all together… from the late night phone calls and last minute vacations to tears and laughter navigating our way through marriage, babies and all that life has brought us.

Sharing clothes: Ashley also struck a pose in the red one-piece while showing off her famous hourglass curves 

‘The best thing about it all is getting to do it with you! I’m so proud to be your big sister [heart emoji] And it was fun to see you rocking these suits!!’

Meanwhile, Abigail couldn’t be prouder of her older sister, who has been an advocate for body positivity throughout her boundary-breaking modeling career.

‘I love to support Ashley in everything she does, especially when it comes to promoting her message of beauty beyond size,’ she said.

‘As children, Ashley and I created a very tight bond that we have been able to carry over to adulthood. Every summer, we would go on road trips together to different states.

‘I’ll never forget Ashley getting stung by jellyfish in Florida. It was hilarious!’ she recalled. ‘I’ll forever be grateful for the sisterly love we have for one another and will never forget the special moments we shared during the photoshoot in Punta Cana.’

Not only did Ashley and Abigail have a great time together on set, but they were both also able to relive their childhood memories.

One shot that shows them sitting in the surf wearing black one-pieces was inspired by a snapshot of them sitting on small statues in a park as children.

In another image, Ashley has her arms wrapped around her sister just like she did when they were kids.

Getting dirty: The model didn’t mind rolling in the sand while showing off her floral two-piece 

Motivation: Ashley created her own swimwear line because she couldn’t find ‘sexy’ and ‘supportive’ bikinis in her size

The two even wore goofy swim goggles to recreate an underwater shot that was taken decades ago.

This isn’t the first time Ashley has starred alongside a family member for one of her campaigns. Just last year, she had her mother Linda Graham show off her figure in a bikini for an exotic Swimsuits For All campaign shoot in Morocco.

Ashley more recently joined actress Sherri Shepherd, Sports Illustrated rookie Tara Lynn, plus-size model Emme, and male influencers Kelvin Davis, Bruce Sturgell, Zach Miko, and Najee Fox in Swimsuits For All’s co-ed ‘Every.Body.Counts.’ campaign

‘We know that women’s bodies are historically more judged and scrutinized, but we also recognize that men are subject to those pressures as well,’ Ashley told Us Weekly.

Life’s a beach! Ashley more recently joined actress Sherri Shepherd, Sports Illustrated rookie Tara Lynn, plus-size model Emme in Swimsuits For All’s co-ed ‘Every.Body.Counts.’ campaign Co-ed: Influencers Kelvin Davis, Bruce Sturgell, Zach Miko, and Najee Fox also participated in the shoot 

‘This partnership shows our continued commitment to represent and celebrate different body types and sizes, supporting the confidence journey for everyone. Guys, we see you too!’

Ashley has been working with Swimsuits For All since 2015, and she recently opened up about her desire to design pieces for women with curves.

‘I didn’t have sexy, supportive lingerie that I could find for my size,’ she told Vogue Australia. ‘And same goes with bikinis, I wanted little tiny string bikinis and nobody wanted to make them for my curvy-a** body, so I did it!’

‘I think what it does is it opens up the eyes to designers also and says, “Oh wow, if she’s making these clothes, lingerie, and swim and they’re selling out, then what does that mean?” Well, it means that the curve industry is a multi-billion dollar industry and that more people should get involved.’
