The Prime Minister may have thanked the ABC for The Killing Season but he and his parliamentarian colleagues slayed fashion at this year's Midwinter Ball.

For the first time in the fundraising event's 16-year history there was minimal fashion victim carnage. Everyone was age appropriate, no skirts were spewing with tulle and tuxedos were tailored. Marriage equality notwithstanding, at least there appears to be bipartisan support for style.

However Margie Abbott and Chloe Bryce, wife of Opposition Leader Bill Shorten, made an unfortunate fashion faux pas with both wearing similar black asymmetric one-shoulder constructions.
