Once seen as controversial and the preserve of celebrities and Love Islanders, the style has become ubiquitous. Is this a sign of body positivity or something else entirely?
There are plenty of places where no one would bat an eyelid at the sight of a thong bikini; on a beach in Brazil or around the Love Island fire pit, visible butt cheeks are practically de rigueur. But my first sighting this year was not while surfing in Australia or sunbathing in the Caribbean, but at an open-water swimming spot, on a rainy day in Scotland.
I should not have been surprised. Tiny swimwear is huge news this summer. It is no longer confined to sunny climes, but cropping up everywhere from lidos to leisure centres – and lochs, apparently.
