Instructions
Review examples of other scary photo shoots and see what items were used in those past shoots. If this is a new genre of the photographer or models, reviewing past work is a great way to get inspiration and ideas.
Decide on the number of wardrobe changes that are going to be made. If you have booked a photographer for an hour shoot, discuss with the photographer the number of times you will be able to change your wardrobe. If time is tight, consider just using different accessories for different looks.
Start with black, whether it is a dress, skirt, pants or shirt, there is a good chance that you will be wearing black at some point. You will also need to know the type of makeup you will be wearing. If the makeup is the scary part of the photo, the wardrobe should not distract from it.
