There are 11 styles in total, with one in particular adorned with Swarovski crystals.
"I like to do active things in the summer because then you’re faking your body into working out," the 28-year-old model told Vogue about keeping up on her fitness goals during the warmer months. "I like to Rollerblade. It sounds really corny, but I do it. It’s so good for your butt, and when you get really good at it and can go backwards up a hill—which I can do—it’s even better."
Meanwhile, it's not even summer and Graham is already winning the season. The body confidence advocate makes out with DNCE frontman Joe Jonas in the band's new music video, and she opened up on set about the stigma surrounding her weight.
"I think I was about 18 years old, and I already had an agent tell me that I needed to lose weight. I had clients tell me I needed to lose weight," she told ET's Lauren Zima. "I still didn't have that gumption to lose weight for them. It was truly, it came from within. It was, 'Are you healthy? Are you happy? Is this a woman you want to hang out with?' And all those answers were no."
"So in that moment, I had to start doing my affirmations," Graham continued. "I started going to the gym more, I started changing my eating habits, and all of a sudden, it all came together and I am still just as curvy and cute and sexy as I was then. It is just my mind has changed."
And clearly, all the hard work and ignoring the negativity has paid off for Graham, who also revealed to ET last week that she has no plans to slow down.
"I think the sky's the limit with so many things I'm able to do right now," she said. "I just have to ask my fans and the women who follow me, 'What do you want?'"
"They just want to know that they can work out, and they can push their body to the limit despite their size," she continued. "I really want to go into the lives of those girls, and live with them, be with them, show them that I went through the exact same thing."
