Boohoo.com’s revenue leapt 35% to £41.3m in the three months to May 31.
The Manchester-based fast fashion etailer’s UK sales rose 27% to £26.3m, boosted by its spring 15 #WeAreUs campaign.
International sales also grew strongly and now represent 36% of group sales. Sales in Europe were up 27% to £4.9m despite what Boohoo described as “significant Euro headwinds”, while in the rest of the world they rose 66% to £10m.
Gross margin during the period was 60.6%.
The number of active customers using Boohoo.com increased by 32% year on year to 3.3 million.
Joint chief executives Mahmud Kamani and Carol Kane said: “We continue to build Boohoo.com for the long term and our clear objective is to deliver sustainable future growth. We remain absolutely focussed on the execution of our strategy to continue to invest in our customer proposition and build market share in our key markets.
“Our investments in the warehouse are on track and we plan to begin partial utilisation of the warehouse extension from July. While we have invested in accelerating our growth during the quarter, our important peak trading periods are yet to come.
“The board’s expectations for full year profit remain unchanged.”
