I did this today:) This look is extremely simple! All I did was after I took a shower and my hair was wet I fish tailed by hair (if you can't fish tail you should check out my YouTube video http://www.youtube.com/watch?v=kgOXgo18hbc&context=C3297b0bADOEgsToPDskIEuYxL_aW7ZzqPUsxkCl1_
Also if you don't want to fish tail you could just braid but I don't think it looks as good. And what I did was I let it dry over night, if your hairs still wet in the morning you could blow dry it or just wait for it to air dry. Then I took it out of the elastic and I sprayed my hair with hair spray and I scrunched it so the waves loosened up. You can shake your hair so it looks more natural too. I might make a tutorial on this is later:)
