Worldwide shipments of wearable devices grew 1.2% in the first quarter of 2018, as numbers reached 25.1m units according to data from IDC. However, that growth was much lower than the 18% year on year growth last year. Analysts put this down to a decline in basic wearables and a shift towards smarter devices and a shift to a number of fashion brands, an area which saw a 28% growth.
