The French are Europe’s biggest consumers of lingerie, and the latest trend is a return to curves, inspired by 1950’s pin-up corsets and cone bras. This is an acknowledgement that women’s bodies have changed over the last 30 years: the majority now sizing 40 and 42. What’s more, the biggest spenders are middle-aged women, who want more support, but refuse to skimp on sensuality. We head to this year's International Lingerie Trade Fair in Paris to see what's on offer for the fuller figure, and speak to lingerie professionals about why what you don't see matters as much as what you do.
