In this song how come?

she's afraid to come out of the water

name the song

She was afraid that somebody would see her "Itsy Bitsy Teeny Weeny Yellow Polka Dot Bikini".

I'm not really sure and I'm probably wrong, but I'm gonna guess 'What I Am' by Edie Brickell and the New Bohemians....even if I am wrong, thanks for making me think of songs that mention being in the water ;)
