There is always three stages of an event. Anticipation, participation and recollection. Anticipation and preparation go hand and foot. While preparing, make a list of your outfits and jewelry. Try on all outfits and lingerie. Remove all tags and labels that can show through the material. To save time and get more shoot time, combine jewelry, shoes and outfits in bags for organization.
Research different websites such as pinterest for ideas on posing and stylization. Consider your make up and decide on weather you are going to do your own or relax and have it done.
