Vannessa Cross rocked a bikini while at the beach on '1000-lb Best Friends.' Here's why she decided on this particular swimwear and what friends said.

Viewers were first introduced to Meghan Crumpler and Vannessa Cross on Season 1 of the Discovery Plus series, Too Large.

At their heaviest, the best friends had a combined weight of 1,000 pounds. Meghan was able to drop enough weight — with the help of Dr. Charles Procter — to qualify for a bariatric procedure. Unfortunately, Vannessa did not make enough progress, and Dr. Procter wasn't able to give her the green light for weight loss surgery.

Now that Vannessa and Meghan have their own show, 1000-lb Best Friends, Vannessa is ready to finally turn things around.

In Season 1 of 1000-lb Best Friends, Vanessa and Meghan tried on swimsuits for their upcoming trip to the beach. Fans were surprised to see when Vannessa came out of the dressing room wearing a bikini that left little to the imagination. "I've always wanted to wear a string bikini," Vannessa declared.

"Oh my God, are you gonna wear this?" a shocked Meghan said when she saw her friend.

"I would love to," Vannessa replied. "I want to show this off."

To that, Meghan said, "You kind of surprise me there. I just never seen nothing that big before — not in a bad way. I've just never seen that in a store, that big. 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."

Vannessa 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.

"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. "Don't get me wrong, Meghan. I hate my rolls. But my brain tells me, 'You're gorgeous.'"

Yet another Redditor shared, "Vannessa’s mobility amazes me, as does her self confidence. I have body issues like Meghan, (that I don’t admit to anyone), so when I see her living life, I say go girl. As obnoxious as she is, I’m happy for her being so confident in herself. I can learn from her."

Hopefully, the BFFs continue to support one another on both their wellness and self-love journeys.
