Most Helpful Girl
Wearing a bikini is a sign of confidence. There are girls who go to the beach who wear bikinis that probably shouldn't, but you know what? I respect them and their courage. I still feel uncomfortable wearing a bikini. I'm fit as hell, but I still look in the mirror and see all the fat I used to have. If I had the courage to be comfortable with my body when I was overweight I'd probably have been happier.
Anyway, the morale of this story is as follows: You shouldn't be concerned at all. You should be proud, and respect her desires flaunt her body.
Believe in her. Even if all the guys stare, she's still yours at the end of the day, and that's what you have to tell yourself.

I mean, what else do you propose she swims in and sits on a hot beach in?
