3. Forky
Made from a spork, some googly eyes, and pure chaos energy. Forky spends most of his time yelling that he's trash and trying to throw himself away, but for now we're happy to have him in our Top 20 costumes list.
4. Supergirl & Krypto
We can never pass up an opportunity to include a furry friend in a DIY costume, so we were thrilled when were saw the new Supergirl movie featured her trusty sidekick Krypto. Save Halloween this year, one easy DIY at a time.
5. Minions
We conducted an experiment, and found that baby babbles are 50% cuter when a Minion costume is worn. Or maybe it’s that kids already speak Minionese, the made-up language from Despicable Me, and now their outfits just match. Whichever it is, we highly recommend making this DIY with our denim overalls, and hoodies in a spot-on shade of yellow.
6. Peter Pan
He never wants to grow up, and honestly? Same. Our little Lost Boy Peter Pan is ready to fly straight past bedtime and into a pillowcase full of candy. Second star to the right, straight on till trick-or-treating.
