If it’s a bridal we are shooting, then besides arriving on time I would encourage the bride to have her makeup and hair done by professionals. I say that because I want bride to feel beautiful, more beautiful than ever. It worth investing into professional help to achieve the best look. It may also give her a good look of how her makeup will look on her wedding day and will give her time to think of what she loves or what she would like to change/add to her look for her wedding day. Therefore, she can adjust the look she prefers for wedding.
