One in a series on the clothes that really popped at Paris Fashion Week.

PARIS — Just give in already: Get a giant white shirt. Wrap it asymmetrically around your torso. Let it slouch off your shoulders. Hack off a sleeve and wear it like a decorative sling.

The spring 2017 Ann Demeulemeester show was by no means the only place where models promenaded down a runway wearing oversized white shirts that looked as though they had been chopped, twisted, turned upside down or otherwise rendered nearly unrecognizable. But it might have been the best.

The conventional wisdom has always been that there were only so many things a designer could do with a shirt — it still needed two armholes, after all. Not so much any more.

One thing that designers both here and back in New York have taken on is the challenge of turning a simple white shirt into something not quite so basic. Surely next season’s “Project Runway” will bring a white-shirt-challenge.

Fashion has a long history of deconstruction, but all eyes seem to be focused on the possibilities in this particular workhorse garment. The design cooperative Vetements expanded plain old shirts to Brobdingnagian proportions. Monte built a brand, in part, by experimenting with men’s shirting, until a button-down was more like an enormous origami project. And this week, designer Sebastien Meunier turned the Ann Demeulemeester runway into master class on white shirts and all that they can be.

He manipulated them into halters and aprons and tunics and dresses. He dissected them so that a white cuff hung off a black blazer or a white collar was lopped off and turned into the equivalent of a scarf. They were sexy togas, prim high collars and odes to déshabillé.

They were all a reminder that the wonder of fashion design isn’t always about whole-cloth invention. Sometimes, it’s simply the ability to see fresh beauty in the mundane.
