WARNER ROBINS -- When opening the door for Halloween trick-or-treaters Wednesday, don’t be surprised if you see a few Avengers.

The superheroes from the movie franchise have been among the most popular costumes in Warner Robins, according to local costume shop owners.

“Hulk has been one of our most popular costumes,” said Kim Wendler, owner of the Party Store.

Down the road on Watson Boulevard, Jerry Bradley, who owns The Costume Shop with his wife, Marion, said the Hulk costumes were also a smash at his store.

“Hulk has been the most popular superhero,” he said.

Both stores are open year-round but know this is the busy time of year. Wendler hired seven more employees for the Halloween season.

“It’s a zoo in here right now,” she said.

Her sales have started picking up in the past few days after a slow start.

For adults, Wendler has sold out of the tuxedo morphsuits, which are like second skin that completely covers the costume-wearer from head to feet.

“We can’t get anymore” of the morphsuits in tuxedo-style, but she does have some in different colors, she said.

Jerry Bradley said his store has seen an upswing in the number of 1970s costumes requested this year.

“We’ve had so many ’70s parties going on,” he said.

From kindergarten to pre-teen girls, Monster High characters and pop star Katy Perry have been the go-to costumes at her store, Marion Bradley said.

This is the Bradleys’ second year in the storefront next to Video Warehouse. They purchased more than 1,000 costumes from a Florida costume store going out of business and had to expand the Balloons-N-More store just to have a place to sell all the costumes. They also rent costumes.

The Costume Shop also sells upscale wigs and professional style makeup to make realistic looking scars and wounds for those who prefer a darker approach to Halloween.

Jerry Bradley is proud of the assortment of costumes he has in the shop.

“We can dress up anyone,” he said.

Trick-or-treating is planned for 6-8 p.m. on Halloween day for all of Houston County.
