It seems as some Maisons are not very interested to design prêt-à-porter collections. Jean Paul Gaultier ins this case did the right "step" , he left Prêt-à-porter to dedicate himself only for Haute Couture.
But same time, Karl Lagerfeld designed always new, "fresh" collections, his *Paris-Salzburg* is very nice, it's what the customers are looking for.
Dolce&Gabbana were shown collection which is similar for fall/winter 2015-2016 and same time is similar, not as "history" or Inspiration" to men collection for summer 2016.
The colours and texture are similar, only one has italian motif print and another chinese motif
