Planning a pajama party is easy. There are some women who even hold one spontaneously. They go lingerie/pajama shopping and then model their purchases for each other in one of their houses. As for the food, they get light snacks or dessert foods. There are also women who want their party to be well-organized. They then hire party consultants to plan the event so they won't have anything to worry about.
