Online clothing retailers modify products

BERLIN — Models testing fashion brands like Adidas, Benetton and Gap are finding that almost a third of the shoes and clothes they try on are bigger or smaller than the size on the label indicates, explaining why many clothes bought online are sent back.

Calculating sizes more accurately could help online retailers like Germany’s Zalando and Britain’s ASOS cut costly returns and improve customer satisfaction.

“If you try on the same brand in a different colour it is sometimes a different size,” Zalando fitting model Savina Bellotto said as she squeezed a foot into a stiletto shoe with a shiny silver buckle that dug into her ankle.

Discounting to shift stock means fashion retailers are struggling to preserve profit margins, and ASOS’s warning of a major downturn caused retail shares to tumble.

Targeting returns, fast fashion firms like Zara and H&M have introduced software that suggests sizes for online customers. Customers type in height and weight, which are processed alongside historic data on purchases and returns.

“It’s a big burden for the retailer,” said Nivindya Sharma, director of retail strategy at trend forecaster WGSN.

“Free returns started off as being a competitive advantage but now they’re the norm.”— Reuters.
