Chinese fast-fashion retailer Shein seeks a $100 billion valuation: That’s more than the combined worth of H&M and Zara, despite Shein selling exclusively online.

Some fashion retailers, like Shein and Revolve, are using data analysis to quickly ramp up production on styles that perform well and avoid spending on excess inventory.

Beyond the chart: Gen Z’s greater focus on short-term gain goes beyond funding Shein hauls and Postmates orders. Finances are a top source of stress for this age group, which grew up during the Great Recession and began entering the workforce amid the pandemic. As a result, many members of this debt-averse generation prioritize financial stability in the short term over saving for the long term.

Online resale platform thredUP asked shoppers in the Bay Area to boycott a Shein shopping event, calling out the fast-fashion company for “encouraging endless consumption” and creating waste. But cost concerns related to inflation could cause shoppers to prioritize price over sustainability, and potentially disincentivize fashion brands from making meaningful changes to their business practices.

Growth rates at ecommerce giant Shein slowed substantially in Q1. These shifts have put the spotlight on Amazon, the giant with about 40% retail ecommerce market share in the US. Amazon’s tepid Q1 performance—when ecommerce growth fell into negative territory—is the clearest sign that the pandemic-driven ecommerce boom is over.

Like many regions around the world, Southeast Asia experienced an ecommerce boom in 2020, as various pandemic-driven social lockdowns encouraged more shopping from home. According to our estimates, ecommerce grew by 35.2% collectively in the region last year, and our newest forecast projects 14.3% growth this year.

Growth from existing enterprise partners like AirBnB and Shein also translated into increased POS and processing volume for Adyen. Global expansion to support more merchants.
