In a trading update the company said that the performance was a result of five store openings and successful product launches.
Burberry chief executive officer Angela Ahrendts - who took up her post in July - said that retail sales accounted for 43 per cent of the business's revenue.
She added: 'Continued strength in outerwear and womenswear have fuelled an excellent retail performance across markets.'
For the year, Burberry plans to spend£50 million increasing its outlets by 19 - nine stores and 10 concessions around the world - giving it an additional 14 per cent of retailing space.
Wholesale results were more disappointing. Sales increased just 1 per cent in the six months to September 30.
The overall figures excluded the impact of buying Burberry's distributors in Taiwan and of converting its Spanish wholesale business to retail.
The company will publish its interim results on November 14.
