How do I get a hairstyle like this one?

I use large hot curlers... and my hair turns out like that. I don't really have hard to manage hair so I don't use spray or anything. So you might have to use hair spray to keep it like that.

Put curlers in damp hair and then sleep in them overnight. If you straighten your hair then you'll need hairspray. If you don't, it'll look more relaxed & natural in the morning.

a curling iron. my hair always turns like that when i curl it.

yeah. a large barreled curling iron. funny to get wavy hair you need a CURLing iron. ;o sorry i`m weird.
