Zalando, Europe's largest dedicated online fashion retailer, lifted its full-year revenue forecast after sales growth accelerated further in the first half.
The Berlin-based company now expects revenue to grow 28-31% in 2015, having previously guided for a 20-25% increase.
"Zalando is powering ahead to take full advantage of the great opportunities in European fashion e-commerce," board member Rubin Ritter said in a statement.
The world's number six in apparel and footwear internet retailing affirmed its full-year target for an adjusted operating margin of 4.5% after posting a 4.1% margin for the second quarter.
Profitability in the second quarter suffered because the group temporarily offered more generous payment terms to customers which resulted in a higher rate of defaults.
Adjusted earnings before interest and tax decreased to €30.2m in the April-June period, down from €35.1m last year. Second-quarter revenues grew 34.1% to €733m.
In April Zalando announced the opening of an insights centre in Dublin, with plans to hire 200 people there over the next three years.
