Now who's idea was it to take the zipper photo? Yes it shows the fastening, but at what cost! Frankly though, I'm baffled at how they managed to make an invisible zipper look so strained on a garment that looks so bulky and loose.
Funnily enough had they done the zipper along one of the straight seams rather than the curved hip seam, this could have been avoided. But that's expecting too much from Jacquemus. Its just too logical and obvious. Also would have cut down on resources (shorter zip, less labour, easier finishing...).
