PORT Adelaide has taken a swipe at Collingwood's guernsey for the inaugural NAB AFL Women's competition, making a none-too-subtle suggestion that the Magpies have stolen their original design.
The Magpies unveiled a jumper with a black background and three white bars for their women's team on Thursday.
It didn't take long for the news to filter over to the Power, who quickly recognised the similarity to the traditional Port Adelaide playing strip the club still uses in the SANFL competition.
In a story posted on portadelaidefc.com.au titled, "Bereft of ideas, Collingwood adopts prison bars for women's team", and attributed to a media department officer with the disclaimer 'The views of the author are fairly black and white, and his own', the Power make it clear they aren't happy with Collingwood's guernsey choice.
"Collingwood has two guernseys in the AFL – the traditional white with three black stripes, and the black guernsey with white stripes which replaced it in 2000," the story reads.
"So, spoilt for choice, it makes you wonder why they chose not to adopt either their traditional jumper for their women's team (or the one worn by the men's team today) and instead pick out this familiar look, inspired from a long-standing design from across the border.
"I mean, it's not like there’s anyone in the AFL preventing them from wearing their traditional jumper, is there?"

The Power continued their rant on Twitter with the post, "@CollingwoodFC will honour @PAFC heritage in 2017 … apparently."
The Magpies hit back straight away, posting a photo of club champion, and former Port Adelaide star Nathan Buckley, with the tagline, "We've been doing so for years."
The Power responded by cheekily asking, "How many flags did (Buckley) win in your black and white?" to go with a photo of Buckley standing on a podium in a black and white guernsey after helping Port Adelaide to the SANFL premiership in 1992.
Buckley won the Magarey Medal as the SANFL's best and fairest and the Jack Oatey Medal as the best on ground in the grand final that season.
It's the only premiership success Buckley enjoyed in his illustrious career, which included seven All-Australian selections and winning Collingwood's best and fairest six times.
And finally ... perhaps ... Collingwood responded to an AFL.com.au request for a comment with, "As all of the AFLW uniforms were designed by Cotton On it's probably not necessary for the club to provide a comment, but thanks for reaching out anyway!"
The Port Adelaide football club was established in 1870 and it began wearing black and white guernseys in 1902.
The club adopted the nickname the "Power" when it entered the AFL in 1997 and added teal to its main colours to avoid a clash with Collingwood.
Port Adelaide declined to nominate for a licence for the inaugural eight-team NAB AFL Women's competition.
So now, the Power will have to sit back and watch Moana Hope and the Magpies do the prison bars proud.

Others weigh in ... and are quickly slapped down
