A bride with red lipstick and red roses is a rare and pretty sight. So is bridal hair with lots of equally sized large round curls on top. This is a very elegant updo she's wearing.
Many curly wedding updos have the curls packed so tightly on top that most all the definition is lost. It's all a big blur.
The distinction of this updo, by contrast, is the curls are more stylishly created with romantic definition. The simple styling method is to make them loose and large.
