The first issue of Asos, which features actress Mischa Barton on the cover, will be sent free to 100,000 customers after today's launch.
Thereafter, the 46-page monthly title will be sold online at Asos.com for£1.
The magazine will feature fashion advice, makeover ideas and clothes sold on the website. Asos chief executive Nick Robertson said: 'A magazine packed with the latest fashion news and trends is the perfect medium to reinforce our fashion credentials.'
If the magazine proves successful, the e-tailer - which boasts over a million registered users - will consider selling it on news-stands.
