She's one of the most successful plus-size models ever. She's been featured in six Vogue magazines and is the first size-12 woman to earn the highly coveted Dolce & Gabbana ad campaign.
"I was working out hours a day, and I didn't know that I could be a plus-size model and be who I was meant to be, ultimately, and be a happy person," she says.
Crystal says she'd like to see fashion adopt a more open approach to models' bodies. "I almost think that they should just have all different types of women," she says. "They should have petite women, they should have thin women, they should have curvy women. So if I'm a young girl looking up at the runway, then I'm like, 'Well, my body type's up there and I'm fine.'"
