I absolutely love Sander's draping skills. The sweaters are very poetic, the pleated looks are incredible, the color palette is divine. I also like his take on the chiffon-wrapped dresses which look much less constricting than what Ford did last season, for example.
The downside for me are the bias-cut dresses in shiny fabrics which could have come out of an uninspired McQueen show in the mid-aughts and the unnecessary menswear looks. I get that he wants to expand into menswear but I don't think he has anything to say yet.
