Gucci has been accused of throwing London Fashion Week into disarray by requesting models fly to Milan early for fittings.
The bi-annual UK fashion event is sandwiched between versions in New York and Milan, which has often caused problems.
It means many of the most in-demand models have to spend hours flying between all the countries as they try to secure shows.
London Fashion Week began last Friday, but on Saturday Gucci creative director Frida Giannini requested models come to Milan for a pre-casting for the label's show this Wednesday.
"Gucci demanded that girls fly to Milan on Saturday to meet Frida to see if she would consider them for her show, which meant Saturday got trashed," Premier Model Management founder Carol White told British newspaper The Telegraph.
