Apparel group Liz Claiborne Inc has posted improved first quarter earnings of $68.8 million, compared with $64.1m in the same period a year earlier.

The company, which partly attributed the profit rise to increased sales from newly acquired brands Juicy Couture and Enyce, also reported a 2. 5 per cent year-on-year rise in sales to $1.1 billion for the quarter.

CEO Paul Charron described the company's first quarter results as "solid".

"Our ability to successfully execute our multi-brand, multi-channel, multi-geography diversification strategy enabled us to achieve record sales and EPS at the upper end of our forecasted range," he said.

"Disciplined execution and the strength of our balanced and diversified portfolio enabled us to more than offset planned lower shipments in our Liz Claiborne and special markets businesses with gains in other brands."

Liz Claiborne's owned brands include Crazy Horse, Mexx and Sigrid Olsen.
