Women will not need to wear a dress unless they want to. Shoes - Select with care. You will be walking a lot. Some parking lots are steep. Even some aisles and walkways in the theaters are slanted.
Women consider flats.
Walking shoes or sneakers are fine too. Comfortable shoes with some soles that grip the ground. Consider long sleeves or consider a light wrap that you can put on and take off. Outerwear - Pick a wrap or jacket for the season. You will be in and out of theaters and buildings and transportation so pick something you can put on and take off easily.
