Dr. Doofenshmirtz beware! You'll be ready to thwart all his evil schemes when you put on this Phineas and Ferb Sassy Girl's Agent P Costume. This package comes with one silk dress inspired by Perry the Platypus. The sleeveless dress is the aquamarine color of Perry's coat and has a picture of his frowning face on the chest. The adorable skirt is full of large pleats and drops down to just above the knees. Remember to wear the brown felt fedora while you're sneaking around to keep Phineas and Ferb from figuring out what you've been up to. Your owners might be busy with their cockamamie projects, but you'll be busy saving the world from Doof's wicked plans. Perfect for Halloween, this comfortable dress will be a big hit at your next costume party.
