Gucci sales plunged as shoppers turned away from Kering’s largest brand that’s undergoing a second design revamp in three years.

Gucci accounts for about half of Kering’s sales and two-thirds of operating profits. A turnaround at the brand has stalled and performance across the rest of the group has also deteriorated amid a global slowdown in luxury demand. Sales at Yves Saint Laurent, the second-largest brand, were also down by 10 per cent in the quarter.

Gucci owner Kering , reported on Tuesday a 15% drop in quarterly revenues, falling short of market expectations, with its finance chief flagging further price hikes in the United States to counter tariffs.
