This year's event involved more international designers and judges than ever before, and they praised the show's unique elements and Dunedin's vibrant fashion community.
But there was no golden chequebook "underwriting" the event for future years, committee chairwoman Susie Staley said.
"We have a core of loyal sponsors who've been with us from the start, but not that ability to effectively underwrite the event. We have to start all over again each year and run a very tight budget," she said.
In her 11th year serving as committee chairwoman for iD Dunedin Fashion Week, and after weeks of 18-hour days, she was unable to say whether she would reprise her demanding role.
"It's very rewarding but it's exhausting. You'll probably have to ask my husband whether I'm allowed to stay on again, and of course it depends on whether the committee wants me to."
Ms Staley is celebrating this year's week of activities as a resounding success, and said there were more people from outside the wider Dunedin area attending events this year than previously.
Both of the main shows at Dunedin's railway station were sold out.
All associated events, of which there were more this year than ever before, were also well attended.
Visiting judges and designers said the iD International Emerging Designer Awards were a drawcard and should be celebrated as a point of difference, along with the Dunedin Railway Station.
"They've told us that what we've got here is something quite amazing ..," Ms Staley said.
Paris-based designer Lutz Huelle, who showcased a collection on the Dunedin catwalk, was impressed with the city's individual style.
"It's not just about frilly dresses and sequins; it's slightly Gothic, it's sporty, it's diverse."
