I think one of the most important things in creating a beautiful updo is breaking the hair down into smaller sections. Oftentimes, due to lack of time or even lack of experience, I see women trying to gather all their hair and quickly throw it up into an updo, when instead it would actually be quicker to take it section by section.
For this style, I did just that. This is a great way to achieve a lot of volume at the crown--which is one of the tell tale signs between a professional updo and a "home" updo. If you can get volume at the crown, you'll make any updo look fancy.
