You would need a nice one piece suit in a pretty color that goes well with your hair and eyes. I'm not sure what the color styles are this year but go with your mom or an aunt and have them help you. Have fun and wear sunscreen or you'll get burned!!!
it all depends on what you are comfortable in and what makes you look the best, as a girl i know that things don't always look good on but may seen awesome on the rack soo i think that you should get a variety of suits like 2 piece 1 piece and all different kinds to see which one really accents your body type, but i would go like one piece considering you are going with a church.
Well I'm the exact same as you! Either you go with like A nice takini with a cute bottoms, or I have this really nice one piece and it has stripes which cross over kind of like a wrap bathing suit! There so cool, my friend who's skinny has one of them to! There for everyone!
