Wonder Woman DIY T-shirt Costume!
Ever since we made our own Frozen t-shirt costumes we’ve been hoping to be hit by inspiration again, looking to recreate this easy DIY costume idea but for another character. When I saw the Wonder Woman movie in the theater this summer, I finally found my t-shirt costume inspiration.
Looking for an alternative to the other Wonder Woman costumes out there? Look no further! Plus our DIY t-shirt idea is super easy to execute, so much so that you can probably make it the night before Halloween (though we’d recommend 2 days before, just to be safe and allow the paint to dry fully).
Supplies needed for our Wonder Woman T-Shirt Costume
- a pre-washed white t-shirt
- metallic fabric paint in silver, gold, red and black
- a piece of cardboard that will fit inside your t-shirt
- paint brushes
- our printable guide (if you need it)
How to make our Wonder Woman T-Shirt Costume
First, spread out your t-shirt and slide your cardboard inside. This step is important because the fabric paint absorbs into the t-shirt material and you don’t want it seeping through your t-shirt and attaching to the back side. It will seep through to the cardboard but once it is dry you can pretty easily peel it off.
Now you are ready to map out your painting. If you are not sure of your free-hand painting skills, measure out the sections of the bodice with pencil and a ruler. You can use our guide to make it easier. But don’t worry too much about your lines being perfect. In this case, as with most crafting projects, completion is more important than perfection. Believe me. I got a lot of the lines wrong, just don’t look too closely!
Once you have your lines roughly mapped out you are ready to paint! Squeeze out a little bit of gold, silver, black and red. For the red of the bodice you will need to mix in a little bit of black to make it a burgundy color. Just a smidge will do it. You can add more or less black to create shading and contouring if you want to get super artsy about it. For the bronze color add a tiny bit of red to the gold.
I painted the red first and then the gold, silver and bronze. Don’t worry too much about your edges because you will go over them later with black which will make them much sharper and clear.
After you’ve painted the base colors, let them dry for just a little bit. While you are waiting for them to dry you can even smooth out any clumps with a dry brush. This will make the fabric paint dry faster. The thicker the paint, the longer it will take to dry so smooth strokes without any clumps will dry the fastest.
Once your paint is dry to the touch you can now apply your black outline detail. Go smoothly but with purpose to create the most even line and most of all be careful not to get in your own way and smudge your lines with some other part of your body! (Not that I did that or anything…)
When you are done, stand back and admire your artwork as a whole, instead of criticizing every little mistake. I promise you, it will look great and anyone trick-or-treating in this t-shirt will get loads of candy in appreciation.
To complete your costume, you can add cuffs and a headband from our Wonder Woman Costume with Homemade Headband, Cuffs and Armbands craft post. Now you’re ready to take on any scary Halloween monsters, and you’ll be comfortable, too!
