Many economists have warned that the world is poised for an economic downturn. The warnings come after President Trump's recent changes to America’s tariff policies. Changes in consumer spending — including their fashion choices — are one potential “recession indicator.”

Erin Delmore, the BBC’s North America business correspondent, explains what a recession is and discusses how people’s purchasing decisions — regarding everything from clothes to salon visits — offer clues to what’s going on with the economy.

We also hear from Caroline Stevenson from the London College of Fashion. She explains how trends come about and unpacks recent trends like the “clean girl” look and the “office siren”.

Plus content creator Leah Holme discusses how she makes mindful purchasing decisions based on the long-term.
