How many little girls do you know who wouldn’t want the ability to have their own Cinderella princess transformation anytime they wish? Costume play trunks are more than just toy chests or storage boxes. They turn playtime into a truly special event that lets imagination run wild.

Pirate Costumes for Kids


Avast, mateys! Pirate birthday parties are a theme that’s perfect for boys and girls of all ages. Our classic Pirates Party in a Box is seafaring and swashbuckling classic, but these pink pirate party supplies are great for girls.

Pirate costumes are tons of fun for everyone, too. Maybe the guest of honor will want to don his or her full pirate garb, but every guest can join the action with accessories like pirate bandanas, paper pirate hats, and pirate eyepatches. After the party is over, you child can store their pirate costumes in a pirate play trunk along with other riches – it looks just like a real treasure chest!

For parents planning a Frozen birthday party for their princess, though, Frozen party supplies pair particularly well with this wintry and icy blue version:

Superhero Costumes for Kids


Pow! Whether you’re into Marvel or DC (or both), superhero party supplies for kids are always popular. The Avengers are particularly big, with a new movie scheduled for next year, but any small superhero in training would love to dress up in superhero costumes for their birthday.

Batman, Captain America, and Spider-Man are top choices for sure, but Supergirl, Batgirl, and Wonder Woman are great superhero costumes for girls. Their sparkly tutu redesigns are perfect for the girly girl who still wants to beat up the bad guys. With a Superhero Play Trunk, your heroes will be ready to fight crime at a moment’s notice.
