When it comes to dressing for fashion week, literally anything goes.
Where else can you wear a kaftan at 7am on a Harbour Cruise, or a pair of pyjamas at a bar at 10pm with 300 of your closest friends?
At Fashion Week Australia in Sydney this week, there has been a definite upswing in the style stakes, as the women have raced to snap every Instagram-worthy moment.
But the guys have given great fashion, too.
At the festival hub at Carriageworks, in inner-city Redfern, Australia's leading street style photographers have been getting snap happy at some of the looks on the gentlemen in attendance.
Journalists, bloggers, fashion buyers and significant others have all upped their game, and taken a few style risks.
The Bachelor's Tim Robards has been setting a high bar in the "significant other" stakes, as he has accompanied his partner, Anna Heinrich, at several events.
At the Misha Collection show, he was a study in monochrome, donning a white jacket, micro-check shirt and black pants, while at Bec & Bridge, he chose a grey suit, which was the perfect contrast to Heinrich's apricot jumpsuit.
Elsewhere, men were branching out with uber-tailored looks, as seen on The Trendspotter's Colin Gold, as well as experiments in denim and "commando chic".

But the king of the suit was undoubtedly Justin O'Shea, former fashion director of mytheresa.com and now creative director at Italian menswear label Brioni.
But on Fashion Week's hump day, things started to get decidedly skimpier.
On Wednesday night, partygoers at the Ivy Penthouse were asked to get all Hugh Hefner and leave their clothes at the door – literally – and don bed wear designed by Ksubi founder Dan Single and his model-preneur wife, Bambi Northwood-Blyth.
Then in the still frigid Thursday morning air, the fashion set hopped aboard a boat on Sydney Harbour for an energetic cruise-cum-show from kaftan queen Camilla.
And it wasn't just the women getting in on the kaftan action. Christian Wilkins, the son of Nine personality Richard Wilkins who works in social media at the network, went all out in a short burgundy kimono with a blue printed wrap.
With two days to run in the festival, there are still plenty of opportunities for the men of Australian fashion to strut their stuff.
Fashion Week Australia, which this year has moved to May to fit international buying schedules, has been showcasing resort wear from Australian and select international designers. Labels including Akira and Ten Pieces have shown menswear. It ends on Friday.
