There is a tendency in summer to opt for the easiest outfit—brought on by chasing kids around, not quite fancying a faff in the heat, or simply being more focused on getting out and about than on what you're actually wearing.

But there is a bolder, far more fun pairing currently doing the rounds, and some of the best-dressed women on the internet are already big fans. Enter: the sarong and shirt.
