This updo has a middle part with both sides being pulled up and back and then tucked into a center part in the rear of the head.
Here is back view of this style.
Two rolls come together in the center on the backside. The top has some height created with some backcombing underneath the smoothed top layer. This photo comes from Portugal Fashion Week – Portugal Fashion Simple Spring/Summer 2012 – Katty Xiomara – Runway.
