Three and a half million customers shopped with Boohoo.com in the 12 months to 31 August 2015 – an increase of 32% compared to the same period in 2014.

The online fashion retailer reported strong website traffic of 182 million sessions, up 27% on the previous 12 months, as well as pushing half a million followers on Twitter, 1.1 million on Instagram and 2.2 million Facebook likes.

Over the last six months, Boohoo's profits rose 39% to £6.27 million, while sales increased 35% to £90.78 million.

Joint CEOs, Mahmud Kamani and Carol Kane, said: "We are pleased to report a successful first half, with strong revenue growth driven by acquiring new customers through our investments in price, promotions and marketing spend. We continue to invest in our brand internationally and our strategy to focus on key markets where we see the greatest growth potential remains unchanged.

"The autumn/winter marketing campaign #WeAreNow is supporting a good start to the second half. We are also pleased with the response to our new app and responsive websites and will continue to invest in building customer value and market reach in the second half of the year."

The eCommerce player has also been ramping up its efforts internationally – overseas revenues now account for 35% of total sales. Growth from Europe was 19%, which Boohoo said was impacted by the weak Euro, while the rest of the world grew 65%, driven by a strong performance in the Australian and US markets. Growth in the UK showed continued momentum with 30% increase in revenue.

Boohoo also completed the redesign of its European websites, including France and Germany, to ensure they are fully responsive. And over the last six months, it also introduced Android and iOS apps to the UK, which will be rolled out to other territories in the second half of the year. According to the retailer, 65% of traffic comes from mobile and tablet devices.
