I think he already had the bulk of the black outfits and just needed to add in a couple more, swap the order around, chuck on extra veils and then you have an impactful first half. What are probably the more last minute of everything actually has more substance than his usual fodder. There's a strange lightness to some of those all black looks that definitely highlight they were made on the fly using general patterns he already has, but that on the fly intuitive thinking has created pieces that are less overwrought.
Still, I'm not fully convinced. As per usual, his references are just way too obvious and gets away with it so easily. I still don't know what he actually represents as a designer, but I know what he wants to represent if that makes sense...
