Kiss the princess goodbye -- this Halloween, kids are trading in their crown for capes.

For the first time in 11 years, princesses haven't reigned over the top costume spot, according to a survey by the National Retail Federation.

Rounding out the top five are animals, Batman characters, and Star Wars-themed costumes.

But kids aren't the only ones planning on dressing up. Expect to see milennials looking like someone from the Batman universe -- inspired by this summer's newest DC superhero movie "Suicide Squad."

The witch puts a spell on adults over 35.

Most who celebrate Halloween -- around 67 percent -- plan on buying their outfit, and it probably won't come cheap.

In total, Americans are expected to spend $3.1 billion just to get their Halloween costume just right.
