How do I get loose wavy hair without frizz *Pic included of what I want*?

Question

So I have hair a bit below my shoulders (when its straightened) that is naturally curly but not like ringlet curls, its half wavy. I dunno its stupid. I wanna find an easy way to get it sorta like this --> http://hannabeth-fan.com/gallery/displayimage.php?pid=1076&fullsize=1

I'd rather not have to blow dry it, and also include tips like if you do it before you go to bed how do I keep my hair nice so its not messy in the morning? (I've heard people say wrap a towel around your head XD) And also products, I've also heard of sea salt spray stuff. But tips are appreciated! Thankiess! :)

Answer 1

I bought a great sea salt spray.  I think it's called waves of envy.  It comes in a blue plastic bottle that's a little hour glass shaped.  But first I put in Sebastian's Potion No. 9.
