Lisa Naylor says it has been increasingly difficult to find age-appropriate costumes for her daughter, as costumes for children have become increasingly risqué.

"You can't just be a kitten — it's a sexy kitten, right?" Naylor told CBC News on Wednesday.

"The message to girls is that you need to be some sexy version of yourself, some vamped-up version that you would never be in everyday life."

The trend has upset Naylor enough to take to her blog and encourage parents to keep Halloween innocent.

Naylor's daughter, Shayla Bielefeld-Naylor, has chosen a 1950s-themed costume for Halloween.

The 12-year-old says she sees girls her age donning more adult-like Halloween outfits, but that's not something she feels comfortable doing.

"I'm choosing to do more of a fun [look] than a sexy look," Bielefeld-Naylor said, adding that she believes Halloween is more about being creative than being fashionable.
