Looks like confidence and beauty run in the family!
After posing for a Swimsuits for All campaign with her mom last summer, Ashley Graham is back at it again. This time around, Graham tapped her younger sister, Abigail, to help model designs from her new summer collection.
Shot on the beaches of Punta Cana, Dominican Republic, the gorgeous campaign celebrates the Graham sisterly bond with a series of "then-and-now" photos of the pair.
"Despite our six-year age difference and busy lifestyles, my little sister and I have always been strong presences in each other's lives," Graham said in a press release.

The siblings obviously had fun modeling Graham's sexy swimwear designs, but they also got a nice blast from the past while looking through old photos together.
"We've shared countless memories together and going through our childhood photos was a trip down memory lane," Graham said.

The supermodel was super excited to have her younger sister on hand to present her latest collection for the size-inclusive swimwear brand.
"Abigail has always been my rock, and I was honored to have her by my side during this photo shoot. Plus, she's a new mom and has never looked hotter in a swimsuit!" she said.

And the feeling was mutual.
"I love to support Ashley in everything she does, especially when it comes to promoting her message of beauty beyond size," Graham said. "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 photo shoot in Punta Cana."

The new mom also revealed how her older sister has had a positive impact on her confidence over the years.
"One time I was trying on clothes and having a hard time making the outfit work, not feeling confident in the outfit. She looked at me and said 'It is just fat, you can manipulate it.' I was like 'Wait what are you talking about?' So she grabbed a boob here and moved one there, smoothed my back out and she goes 'Boom now you look flawless.' So ever since then, all the 'tabooness,' so to say, has gone out the door for any outfits that I want to try on," she said.
And that's true sisterly love!
