Online fashion retailer Asos has revealed a 15 per cent rise in UK retail sales for the three months ending August 31st 2012, in financial results released today.

While UK retail sales now stand at £49.9 million, total sales rose 31 per cent to £141 million while total international sales saw a 42 per cent boost to £91.1 million in its fourth quarter.

Over the period, total group sales increased 31 per cent to £145.1 million, driven by a strong performance across its US operations, which reported a retail sales rise of 65 per cent to £13 million.

EU sales grew 22 per cent while the Rest of the World saw sales rise 53 per cent as the pure-play e-tailer built on its popularity with fashion-hungry customers.

Five million active customers used the site over the period, up 35 per cent year-on-year and Asos CEO Nick Robertson welcomed the solid results.

He commented: “Profit for the five months ended 31 August 2012 and pro forma full year, are expected to be in line with expectations, and we approach our new financial year with continued confidence.”
