The nightie dress is a sartorial saviour in the scorching heat, offering a chic and effortless way to stay cool. This trend, which has been making waves on the runways of McQueen, Fendi, and Christian Cowan, is now making its way onto the streets. Celebrities like Madonna and Charli XCX have been spotted in lace-trimmed slip dresses, solidifying the trend's popularity.
