To add some extra detail to the costume, consider adding gray work gloves to mimic the texture of a shark's skin. These can be found at most hardware or outdoor supply stores.

Finally, finish off the costume with a pair of gray fishing boots to create the impression that you're swimming through the water like a shark. Lavagirl has fluorescent bright pink hair down to her shoulders in a somewhat wavy style. One of her most defining powers in the film features her hair lighting up neon pink when she uses her extraordinary abilities.This layered felt does not stretch at all. The top is a little tight to get on, I may have to add a zipper if she wants this to remain part of her dress-ups, so I choose to just use some fabric painton the pants (we need to have the stretch and movement in the pants). When using her powers, Lavagirl’s hands come alight with golden yellow fire, one of the most unforgettable 3D moments taking place in the film. You can use LED party finger-lights to create a similar look, or you can use UV glow paint or yellow Halloween makeup for this additional feature. Sharkboy: Sharkboy could easily rival Jaws with his own set of pointy shark teeth! To get a similar set of teeth as this superhero’s, you’ll need some fake costume teeth. Any pointed Halloween monster teeth will work. Outfit:

Then I glued the “lava” down. I chose red sequin ribbon cause they would give me the movement and what girl doesn’t love sequins. If you're going to be Sharkboy this Halloween, you'll want to embody his confident and headstrong personality. Sharkboy is not afraid to speak his mind and is often seen as the leader of the group. However, he also has a caring side, especially when it comes to LavaGirl. But if you and your kiddo are big fans of The Adventures of Sharkboy and Lavagirl,you already have all the intel you need to help your little one channel their inner superhero. And we're here to help! With your knowledge of the story, the powers, and the heroid adventure, we can offer up the outfit to complete the transformation! Design & Details

DIY Costume Items

Sharkboy has short, dark brown hair gelled into small spikes on his head. Recreate this style for your own hair using liquid hair gel, or use a dark brown cosplay wig with formed spikes to get a similar look. To pull off the look of Sharkboy, you'll need a few key items. First, start with a gray compression shirt and matching pants. These will provide the base for the costume and help create Sharkboy's sleek, aquatic look. Pair these with a gray life vest to mimic the appearance of a shark's skin.
