Halloween may be over, but the parade of horrifically offensive costume ideas marches on.

A pair of university students found themselves on the front page of the UK's most widely circulated newspaper after winning a Halloween "fancy dress" contest with their "blazing Twin Towers" tribute to the hundreds who perished on 9/11.

Amber Langford and Annie Collinge, whose getup came complete with burning airplane models, toy humans leaping to their deaths, and American flags shrouded in smoke, took home £150 ($240) after being voted best dressed by attendees at the popular Chester nightclub Rosies.

Making matters more mind-boggling, Amber's father is a retired airman "who was flying jets in the US" on 9/11, according to The Daily Telegraph.

The subsequent fallout has forced Rosies to pull the plug on all their social media properties, and the club's parent company, Stonegate, has vowed to conduct a "full investigation."

The University of Chester has also launched its own investigation into the incident, "with a view to taking the necessary action."

The two 19-year-olds have since issued an apology which rivals their costume choice in its astounding awfulness, saying, "We never meant to be offensive, but we apologise if any offence was caused. The idea was to depict a modern-day horror that happened in our lifetime and was not intended as a joke."
