Style icon Clive Palmer has unleashed a colossus of cool in Canberra this week.
Having arrived at Parliament House on Tuesday in a silver 1972 Rolls Royce Phantom, the member for Fairfax marched through the doors this morning sporting a rare Onassis knot.
It's named after Greek shipping magnate Aristotle Onassis (husband of Jackie O, the widow of JFK, not the one who works with Kyle), although whether he can be credited with its invention is unknown.
Nowadays the knot is uncommon, but was still trendy in some parts of Manhattan in the late '80s according to the New York Times.
Mr Onassis was also a wealthy man - indeed, his granddaughter and heir Athina purports to be a billionaire.
Like Palmer himself, with this knot what you see is what you get.
The Onassis is deceptively simple: at the end of a standard schoolboy or Windsor knot, you simply loop the wide end of the tie behind and over the existing knot.
Because the knot itself is covered, the Onassis is *the* choice to accentuate a nice tie, according to the experts.
Where the red-and-black stripes fit in Palmer's hierarchy of ties we can only guess.
Perhaps he wore it to dinner with Malcolm Turnbull on Wednesday night.
A knot website in the UK notes the Onassis is for "informal occasions" and "not suitable for work".
How to tie an Onassis knot: For those wishing to emulate the billionaire's style, here's a demonstration using the four-in-hand base. Some recommend using a clip underneath the knot to give the proper, narrowing effect.
