The currency fluctuations caused concern for Italian mills showing at the event in Milan last week.
Many told Drapers that they were sacrificing profit margin to retain key US and Japanese customers.
Exhibitors at the show, which encompasses Idea Como, Moda In, Shirt Avenue, Prato Expo and Idea Biella, said the weak dollar and yen meant products were up to 30% more expensive for core US and Japanese customers against this time last year.
Silvio Albini, president of Shirt Avenue and owner of mill Cotonoficio Albini, said: “To be loyal to customers we have had to sacrifice our own profit margin.”
Milano Unica is expected to move from its site in Milan to Rho on the outskirts of the city in 2009 or 2010.
