LONDON, Nov 16 (Reuters) - Online fashion retailer ASOS (ASOS.L) posted a 9 percent rise in first-half profit and said sales remained strong in its second half, with a pick up in overseas demand offsetting slower growth in Britain.

The firm, which targets internet-savvy 18-34 year olds looking to emulate the designer looks of celebrities like Kate Moss and Victoria Beckham, but at a fraction of the price, said on Monday it made a pretax profit of 4.4 million pounds ($7.3 million) in the six months to Sept. 30.

In September ASOS had said first-half profits would be "marginally ahead" of the same time last year.
