Phineas and Ferb Halloween Costumes

by Megan

This year we made Halloween costumes a family affair! Carter has been obsessed with Phineas and Ferb for a long time, so we decided we’d go as characters from the show. Our Phineas and Ferb costumes turned out perfectly, except for the fact that, as a few people pointed out, we didn’t have a Ferb!

Phineas and Ferb Halloween Costumes

Phineas Costume

Carter went as Phineas. I sprayed his hair with temporary red hair dye. It’s still a little pink.

My mom found a gray and orange shirt and painted the gray stripes yellow. She also painted some white onto his blue shoes to look like Phineas’ shoes. He brought his stuffed Perry the Platypus to school on Halloween, and during the costume parade, several parents and kids yelled out, “It’s Phineas!”

Isabella Costume

Vanessa was Isabella, but she didn’t know it. Yeah, I’m that mom who told her daughter she was going dressed as a “pretty princess” even though we dressed her up to look like Isabella!

She got mad anytime Carter said she was going to be Isabella, but “pretty princess” was acceptable. I do not expect to get away with this next year!

Isabella is a very easy costume to pull off! You just need a pink/purple hairbow, tank dress, and a white t-shirt underneath. Add some white socks and pink or purple shoes and you’re good to go!


Candace Costume

I went as Candace, Phineas’ older sister, who is always trying to “bust” her brothers. All you need is a white skirt, sleeveless red turtleneck top, red socks, and white shoes. A red belt would be a nice touch, and hey if you want to attempt the red hair dye… (I did, but it didn’t do much on my dark hair).

I didn’t get many pics of my costume, but if you scroll down you’ll see me with the whole family!

Dr. Doofenshmirtz Costume

Daniel went as the villian, Dr. Doofenshmirtz, and Harry was his nemesis, Perry the Platypus! SO cute.


This is an easy one. White lab coat (or if you’re dressing up a kid- one of Dad’s white button-downs!), black shirt, olive green pants, and black shoes. And try to look kind of evil. Or at least sneaky.

Perry the Platypus Costume

Harry was the cutest little platypus ever!

His costume was pretty easy too. We ordered the hat from Etsy and found a turquoise sweatsuit at Kohls. It was actually in the girls section, and the top had sparkly hearts on the front, so he wore it inside out!

For his platypus tail, I cut two pieces of orange felt, sewed around the edges and then criss-crossed the tail a few times to make a pattern. Then I sewed it to the bottom of his sweatshirt!

Our favorite babysitter came trick-or-treating with us, and she managed to snap this shot of the whole family. Thanks, Madison! It’s like a miracle photo. Everyone is looking at the camera with an acceptable facial expression! It’s not great quality because it was dark, but I love it!

On Halloween night we went trick-or-treating in our neighborhood, and I put my iPhone in the stroller and looped the Phineas and Ferb theme song. It entertained…me.

At several houses, Carter told people who he and Vanessa were, and they thought he was introducing himself.

“I’m Phineas, and this is Isabella!” “I’m Susan, nice to meet you!”

Then, on Friday night, we went to our church’s trunk-or-treat, and the kids both had very full buckets of candy! I managed to have a sugar-free Halloween, but I can’t say that I haven’t been tempted by the Reeses and Rolos and Kit Kats they got!

It was a great Halloween!

Love it? Pin it!

Phineas and Ferb is one of the best kids shows, and costumes are pretty easy to put together! Check out our whole family Phineas and Ferb Halloween costumes!

So adorable! Where did you get the components of the baby perry outfit? Particularly the sweatsuit in teal!

Megan October 16, 2014 - 1:13pm

The hat came from an Etsy shop, and the teal sweatsuit came from Kohls, in the girls department! He’s wearing it inside out, because it had a big sparkly heart.

Awesome, thanks!
