Discount chain Best and Less, which twice vowed to remove the bra collection for toddlers from all its shops after parents and lobby groups branded it the "adultification of children", are still selling size 2 and 3 of the undergarments.
The outraged parent groups have called for a boycott of the stores selling the toddler bras, the Daily Telegraph reported.
Pop idols including Rihanna and Miley Cyrus, have been blamed in part for the retail trend of "sexploitation" of young kids because of their skimpy stage outfits, exposed underwear and sex-laden lyrics.
In April, the company promised to pull the toddler bra stock from its stores,
but the controversial underwear was still for sale in Townsville, Brisbane and Cairns stores on Friday.
