Office Girl in Tightly Bound Ultra-Conservative Formal Chignon

Back view of a brunette with tight updo and black scrunchie. Looks like she's also got a bunch of hairclips to make sure everything is under control.

One of the difficulties of this kind of up style is controlling the hair on the back of your neck. It is more pronounced for girls with dark hair and pale skin as in the above example. You can't see the mess back there but everyone else can.
