I think the show was a bit like an animated look-book, the styling pretty amateur, the overall vision for the show was not strong enough, but deconstructed there were some nice pieces on the catwalk, so it wasn't the design team's fault.
I don't think it was post-war (a term usually given to Post-WWII). I think there were deliberate refs to post-WWI, but globally so chiffon flapper dresses and fringes under boiled wool oversized (borrowed?) coats. Also, nods to Soviet-style, socialist realism/utility /uniform-y type things going on. Although the Soviets would not have been using the finest lamb's leather or silk. I enjoyed most of the colours too and the different varying degrees between light-eating matte-matte and wet-look, high-gloss-high-shine.
I can't comment with authority on the evolution of catwalk bags, except there were just too many, tt seemed like every model was carrying one. Since they were uniformly the same hue/tone/tint of the outfits worn, they ruined every respective silhouette and compromised the value of the accessory's inclusion.
