I have short curly hair, styles to do with it?

Right now if I straighten straighten it, it would really be around a itty bit past my shoulders, but when I leave it natural, its at my shoulders...what styles should I do? Oh, and I swim all the time, and need something to do with mositurizing it because the chlorine, it's blotchy right now, a brown with black spots because I'm trying to get the black out. Any ideas?
