Dress Up Key

The Dress Up Keys (ドレスアップキー) are the main collectible items for the Go! Princess Pretty Cure season. The Dress Up Keys come in the Cures respective theme colors and also look like their outfits. They can also be used to activate the girls transformation when inserted into the Princess Perfume. Once all Dress Up Keys are collected, the Gate of Dreams will be able to be opened so the Pretty Cure can protect people's dreams. Power of dreams dwells within the keys.
