A bikini that is designed to be worn by plus size women. It is cut differently than more traditional bikinis so as to make the wearer feel less self conscious about being fat.
"I'm 5'4'' and I weight 250 lbs. I don't think I could ever wear a bikini. I'll just have to stick to a one piece"

1. "Why is that girl wearing a diaper to the beach?"

"It's not a diaper, it's a fatkini."
