The annual Pride Game match between the two clubs will now see the Sydney side play in a stunning new kit, designed by Nike that express "a passion for sport, diversity and inclusion, and the community".
The jumper features a rainbow 'V' to represent the LGBTIQ community, while players will also wear rainbow socks.
In a statement released by the club on Monday, Swans chief executive Tom Harley expressed the important role the club and league holds in representing the LGBTIQ community and fans.
“Our Pride guernsey reflects the importance of being an inclusive club and we want everyone to feel welcome at the football,” Harley said.
“We’re thrilled to introduce our new Pride guernsey which reflects on our connection and commitment to the LGBTIQ community.
“Pride Game is always a highlight on the calendar and although we can’t be at the SCG with our members and fans this year, we know our supporter base will come together to celebrate, no matter where the game is held.
“It’s exciting to be able to launch this guernsey and I look forward to seeing the team run out in it against the Saints in Round 21.”
St Kilda have previously worn special guernseys for the pride match, while the AFLW have also implemented Pride jumpers in recent years.
"It's more than a game... we've created a great platform within women's football to generate an inclusive environment."
