Semi-Homemade Despicable Me Agnes Costume

by Tonya Staab

This semi-homemade Despicable Me Agnes costume is perfect for girls of all ages this Halloween. For a Despicable Me birthday party too.

Do you remember when I took the kids to Universal Studios, Orlando over the summer?

Well, while we were there I told each of the kids I would buy them a souvenir to bring home. Of course Marisol chose the biggest unicorn from the Despicable Me store that she could possibly find … yes “It’s so fluffy, I’m gonna die!” She naturally named it ‘Fluffy’. 

So, come time to decide what elaborate costumes I have to make for Halloween, she decided that she just had to be Agnes so she could go trick-or-treating with Fluffy. I must say I was just a wee bit excited about this, because I knew that very little actual work would need to be done by me for this one.

What you need

  • Overalls with red buttons – instructions below
  • White sneakers
  • Yellow socks
  • Yellow and brown striped t-shirt – instructions below to make your own
  • Red scrunchie
  • Black hair spray
  • Brown face paint – or you could use an eyeliner or lip liner
  • Unicorn


There was a little crafting to be done. How many pairs of overalls have you seen with red buttons on them, or pre-striped brown and yellow tees?

Agnes overalls

They came with a traditional buckle that just wasn’t going to do. I removed those, hemmed the bottom of the shoulder strap, hand-stitched buttonholes, and then stitched on large red buttons.

Striped tee

  • Yellow t-shirt
  • Fabric paint
  • Sponge brush
  • Tape – I used the Duck Brand ‘Ducklings’ tape, which peels off fabric really easily
  • Something to place inside the shirt to protect it

Make stripes on the t-shirt using the tape and paint in-between. It’s that easy.

Note: Don’t forget to put a piece of cardboard inside the shirt so the paint doesn’t go through the fabric to the other side.

The final touch to the costume was a few extra freckles on her face.

She wore her new Agnes costume during the past week to the school Halloween bash and was thrilled to win the 2nd-grade costume contest, and for those who know Miss M and how shy she is, it took a lot of courage for her to enter. Although, she was a little embarrassed when the local high school girls who were volunteering at the event kept asking if they could take photos with her.

She and Flynn both got to showcase their costumes on the Fox 5 San Diego morning news Halloween costume segment too.

oh yes, not having to use a sewing machine is a huge plus for me too … I'd have to find it first on my craft table, and don't even get me started on threading it.

Bre October 29, 2013 - 9:16 am

I miss you too, Tonya….very much!! 🙁 If you guys see Brad Will at Fox 5 tell him you are friends of ours. He is Josh’s best friend and a great family friend of ours. He’s Uncle Brad to my kids…lol. Anyway, I will send you a pic of my kiddos. They are all growing up way too fast. We need to get together next time we are in San Diego. We were just there a few weeks ago for the kids bdays. Give your lovelies hugs for me!!

Hi Jackie. Tie the hair into a very high ponytail on top of the head. Brush the hair upward and spray using an ultra hold hairspray. Use a hand towel or paper towels to shield the skin when spraying the black hairspray over the top. Once dry add the red scrunchie.

Can you share a little more about how exactly you got the hair to stand straight up?
