The woman, known only as Shannon B, was so outraged by the costume that she launched a petition for Kmart to remove the 'offensive' product.
Each year 12 million children (girls as young as six years old - the same size as this 'costume') are sold or married off by their family without their consent she wrote.
Child marriage means child abuse and torture in its worst forms - paedophilia, child rape, child slavery, child sex trafficking she said, adding that Kmart had a social responsibility to uphold.
After just two days and a mere 124 signatures, Kmart removed the costume from their stores and issued an apology for any offence caused.
'Kmart Australia regrets the decision to range the bride costume,' a spokesperson said.
'It was not intended to cause offence and we sincerely apologise.'
However, the costume has left people divided, with many claiming that the woman had read too far into the situation.
'Let kids be kids,' one person commented.
'You need to get a new hobby,' wrote another.
