The clothes horses were appearing in an installation-style show for gothic Sydney label Serpent & The Swan when they became, according to onlookers, disoriented and faint. The dark 45-minute presentation, set inside CarriageWorks theatre The Box, featured models standing completely still in assorted poses underneath strong lighting while groups of guests were brought in and out of the room. Noticing the poorly girls, Fashion Week volunteers and some publicists removed the models from their posts to be treated by the onsite medical team. While some passed out backstage, all four were seen vomiting behind the scenes. A spokeswoman for Serpent & The Swan, helmed by sisters Hayley and Lauri Smith, said the situation was heat-related and had nothing to do with malnourishment, which doctors have said has been a problem at this year's event. "The Serpent & The Swan team and (organiser's) IMG had food, lollies and water stations set up backstage before and during the show which our team made sure was utilised by all models in the lead-up to the show," she told Confidential. The combination of standing still under the heat of the spotlights and the large crowd caused the girls' illness. After the episode, additional airconditioners were brought into the space to ensure no one else was affected. I'm pleased to report that all girls are now happy and healthy.
