The viel historically was designed to cover the face of women in many cultures. In cultures where arranged weddings were the norm, the groom would not see the bride until after the ceremony, thereby being too late to change his mind. More likely, today's veils are a part of social fashion and don't relate to etiquette. The comfort issue that brides find is that when embraced by family and friends, the veil becomes a hazard to your neck and hairdo. Take it off if you like with no worries.

That is what most brides do! In this way, they can dance, enjoy themselves and move around easily.
The veil is traditonally for the ceremony. Many brides keep it on during photographs, then it is usually taken off during the reception. Sometimes, if the bride's veil is quite long and she likes the idea of wearing a veil throughout the entire day, she will slip into a shorter easier to manage veil just for the reception.
