Sooo, I gotta question

Is it ok for fat/overweight people to wear bikinis? I am 5'3 at about 230lbs. I've been wearing a bikini for the past few days while I'm in Cocoa Beach on vacation. The thing is, whike I feel ok most of the time, sometimes, I feel like a damn cow in it, simply because all the skinny chicks with ribs and hip bones that are poking out are wearing next to nothing. The majority of my friends say that I look fine, and that I should stop worrying. Only a few of my friends have seen this particular piece of swimwear on me, and I'm getting good review. But, I just don't know, it kind of feels like the world is laughing at me for trying to feel a little bit better about myself. Anyway, just leave me a comment and I'll get back to you. Adios por ahora.... Bye for now.
