Heavy girls that wear bikni?

no offense or anything, im just curious. i am pretty skinny with just a little chub here and there and i barely have any confidence wearing a bikni esp. in front of boys. do you wear them just becuase, you might say "screw what people think, im gonna enjoy life", or " i like to show off my junk" or "it's what everyone else is wearing?" do you have confidence or are you actually insecure in your bathing suite?
