Sales at Burberry rose by 13% on an underlying basis to £539 million during the first half of the year.
Retail sales at Burberry rose by 14% to £245m for the six months to September 30, thanks to improvements in the supply chain, which enabled more on-time deliveries of autumn stock.
Burberry said innovation in iconic outerwear and accessories also helped to drive sales. Comparable store sales were up 3.4%.
In the first half, Burberry increased its average selling space by 13% year-on-year, with five new stores, 19 concessions and four outlet stores.
Wholesale revenue increased by 15% to £254m, with good performances from North America and Europe, although Spain "remained challenging" across both the wholesale and retail divisions.
Total licensing sales fell 3% to £40m.
Burberry chief executive Angela Ahrendts said: "I am pleased with Burberry's performance in the first half of the year, against the background of an increasingly challenging external environment. The strength of our diversified business model was again demonstrated as we delivered double-digit growth for the fifth consecutive six-month period."
She added: "While we expect trading conditions in the all-important third quarter to remain volatile and uncertain, we continue to focus on our proven product, regional and channel strategies to drive long-term growth."
In the second half, average retail selling space is expected to grow by 12% year-on-year, but wholesale revenue is expected to be flat with sales in Spain forecast to decline by 20%.
Licensing revenue is expected to be slightly down, as demand in Japan softens.
