The border with the triangles and plus symbols did threw me off at the beginning. But on the picture from the Pret a Porte show the scarf does look like it folds like a cotton scarf would, that's why I thought about this 90 men's- carree from the german web site. I do think the patterns match....
The scarf on the website ends with a dark border, while the one on the picture has a brighter border (with the triangles) but this brighter border comes after the dark border. I figured the show version of the scarf is slightly different than the actual version that hits the stores months later. Like it was a few years ago when "Couvertures et Tenues" GM C/S came out. It was a fringed shawl on the runway, but only a rolled one on the stores... (I even thought, maybe the triangles are just color samples from the print on the scarf that get cut out at the end!?!)
