I did a dry twistout on previously blown out hair and then styled it. The style consisted of two humps and then loose hair in the back.
Heres the style:
left side
right side
To achieve this style I did a normal hump in the front and then I rolled a horizontal section of hair towards the middle of my head from both sides creating the second long hump at my crown. I then bobby-pinned it down. It was really easy so feel free to duplicate it!
