Sadie Brook remembers how she started. "There was a pop-up ad on the Internet that said Models Wanted and I thought, "I have some pictures to send. I wonder what kind of feedback I'll get." So I emailed the pictures. But it took a long time to get me to XL Girls because I was hesitant. I was like, "I wanna do it, but then again, I don't want to feel like I did something I shouldn't have done." So I talked to some of my closer family members and said, 'There's something I'm thinking about doing. Would you have a problem with it?' And they didn't."
