"I was influenced by ideas of escaping and, I guess, animal behaviour.
"Also playing on this mannequin aesthetic that runway models can look like.
"I was flipping through a magazine and saw a picture of a Christian Dior runway show, and the women had such incredible high hair - so all the dancers wore these huge wigs; to me they looked like lions."
The piece was the catalyst for Final Dress, which has its own sense of style: the costumes, dresses from the 1950s-60s, were all sourced from vintage stores on Cuba St in Wellington.
But while fashion appears in some of his pieces, Keigwin believes it is pop culture that is more influential to his work.
"At times my eye goes to fashion, or a runway show, but it's not necessarily high fashion that I'm thinking about. It's more pop culture, people I see on the street."
People on the street played a part in another important job: staging the opening show of Vogue's Fashion's Night Out in 2010, the biggest public fashion show seen in New York that showcased Vogue's top trends.
Keigwin got the job with the help of a "little champion" in his life, Damian Woetzel, a former principal dancer with the New York City Ballet and current cultural ambassador who sits on a committee with US Vogue editor Anna Wintour.
"She asked him, as a dancer, who he would recommend to choreograph this fashion show, and he suggested me."
After attending a few of his rehearsals, Wintour commissioned Keigwin to produce the mammoth public runway show that launched Fashion's Night Out, held outside at the Lincoln Centre and featuring 175 high-end runway models (think Naomi and Giselle; top models he describes as being "very playful"). His job involved creating the walking patterns on a circular catwalk, rather than the traditional straight up and down runway.
"Everyone is very real; they're all stereotyped but people can break their stereotype," he remembers.
"Anna Wintour had a wonderful sense of wit; was a great decision-maker and a great business mind. She was very punctual, but also creative and willing to collaborate."
After attending the premiere of this new production in Auckland next Wednesday, Keigwin will fly to Washington DC for a new show with his company at the Kennedy Centre before heading back to New York to create a new show to premiere in June.
