How to put it together

1
Choose your character: decide whether you are going as the energetic Phineas or the quiet genius Ferb.
2
For Phineas, put on the orange and white striped t-shirt and pair it with the bright blue shorts.
3
For Ferb, tuck the light yellow collared shirt deeply into the high-waisted purple shorts or pants.
4
Fasten the thick black belt tightly around the waist of the purple shorts to mimic Ferb's signature high-waisted cartoon silhouette.
5
Wear blue sneakers for Phineas, or dark tennis shoes with white socks for Ferb.
6
Carry a green platypus plush toy to represent their pet, Perry.

Makeup & hair

For Phineas, style your hair in messy, spiked-forward sections using strong-hold gel, or use temporary orange hair spray. For Ferb, use green temporary hair color spray or a short green cosplay wig styled with a slight side sweep.

Tips

Keep the colors bright and solid to maintain the vibrant, clean look of the animated series.
If you can't find an orange and white striped shirt, buy a plain white t-shirt and use orange fabric paint or masking tape to create the stripes.
Carry a toy wrench, blueprint roll, or a Perry the Platypus plush as a fun, character-defining prop.
