Fashion e-tailer Boohoo is to start selling its products through Asos from the middle of May.
The offering will comprise a capsule collection of around 100 items and will be sold on a trial basis as Boohoo looks to extend brand awareness in both the UK and international markets.
Last month Boohoo said it would look to make a "step change" in its marketing efforts with marketing expenditure set to rise to 18 per cent of sales, compared to 14 per cent of revenue, estimated to be around £15m, which Boohoo.com spent in 2014.
Meanwhile Asos reported pre-tax profits of £18m for the six months to 28 February, down from £20.1m in the previous year.
Retail sales grew 17 per cent to £536m, while sales in the UK jumped 27 per cent.
Boohoo has three million active customers, with mobile representing almost half of all sessions and daily unique visitors.
