It's going to be a special wedding for Disney's Cinderella because there are actually two weddings. In one of them, you get to style her just like in the time period that the movie took place, meaning she will have a medieval dress and style, while in the second stage you also get to dress her up in modern wedding clothing. You can do this with the awesome game Now and Then Princess Wedding.
In either of the stages, you start out by choosing the hairstyle you think suits, Cindy, the best. Select the dress, the veil you think suits it the best, a bouquet, and don't forget of accessories like jewelry. You do this in a medieval style, a modern one, and in the third dress up the level of the game you get to mix the two styles together and create a hybrid look!
Now that you've understood how this simple and fun wedding dress up game works, make sure to give it a go right away, and enjoy yourself like only here is possible!
