Storm Cloud Costume

Another look from the The Unplugged Family. Flashing LED string lights make it look like real lightning!

To make the storm cloud: Start with a black sombrero. Cover top of hat with flashing, battery-operated LED string lights, using tape to attach. Add a generous layer of stuffing. Add another layer of lights, and top with more stuffing. Hit a few times with short sprays of gray spray paint to give it a dark and stormy look. Cut out large rain drop shapes from blue felt and attach to hat with blue yarn. Complete the look with black clothing and neon rain boots.

Starbucks Cup Costume

“This has got to be the easiest and quickest costume I’ve made so far,” said the mom behind this costume, who posted it on her Instagram @creativearttable. The life-sized Starbucks cup she whipped up at her tween's request is not only super easy and adorable—it won a homemade costume contest too! The secret to the straw? A self-adhesive glitter foam sheet.

Fairy Costume

Fairy is one of those Halloween costumes that's good for any age—and you can always repurpose the wings in another costume another year. Use a favorite dress as the base.

For the fairy wings, check out the tutorial at Andrea's Notebook. They're a little different than the wings pictured here, but we love how approachable her instructions are.

Aviator

A tween who loves all things aviation—or who's always poring over boxes of old family photos from generations past—will take off in this vintage-style aviator look. They might imagine themselves as Amelia Earhart, Orville or Wilbur Wright, or Bessie Coleman.

What do to when you know your tween is going to wake up three inches taller any day now?

If the pre-buzz about Halle Bailey's turn as Ariel in Disney's live-action The Little Mermaid (2023) has inspired your tween, it's time to show off her fins. Of course, you can buy an Ariel costume, but if you're crafty, this homemade version is so pretty.
