‘Sexy’ Ken Bone costume has a question: Trick or treat?

The votes are in: Ken Bone is fast becoming the “it” costume of Halloween, with one company saying it sold out of an outfit inspired by the debate audience member within hours.

{mosads}Yandy.com, the same retailer behind the risqué Donald Trump- and Hillary Clinton-inspired “Donna T. Rumpshaker” and “Capitol Hill” costumes, respectively, which ITK detailed last month, says it began taking pre-orders on Tuesday for its “Sexy Undecided Voter” costume. Within four hours, the company says it sold out of its planned initial run of the $100 ensemble.

The red crop top, blue high-waisted pants, white undershirt, glasses and mustache — along with a microphone — are a skin-showing take on the now-infamous get-up that Bone wore at Sunday’s presidential debate in St. Louis.

Bone won over many viewers with his bright, casual attire when he asked a question on energy policy of White House hopefuls Trump and Clinton.

Bone said late Monday he was still undecided about whom would get his vote.

Yandy.com says it’s now going back to its manufacturing facility in an effort to produce more costumes, which will be available for pre-order soon.

“We are always prepared to move fast and get a viral sensation into production, but the popularity around Ken Bone has been difficult for even us to keep up with,” Yandy CEO Chad Horstman said in a statement.
