I mean, I've been that big. Never mind."Fast-forward to Episode 6, and it turned out that Vannessa did decide to wear the bikini to the beach. "It's beautiful. It's definitely unique and I love the prints," a hesitant Meghan told her. "I'm a little afraid that it's gonna fall off, It looks like it's not got much attached. And I wish I had your confidence."\n\nVannessa told cameras, "I am so excited to finally put this string bikini to good use. I feel beautiful, courageous ... nude."As Meghan, Vannessa, and Tina Arnold were sitting in the sand, people-watching before getting into the water, Meghan lamented about how she wished she looked like other beach-goers. That's when Vannessa stepped in with some insight into her confidence.\n\n"Let me tell you something, baby. It's taken a lot for me to show up with nothing but my bikini on," Vanessa told her.
