Consumers care more about what a brand stands for now more than ever. Burberry's decision to burn excess inventory may have been brushed off in the past, but people want to be associated with brands that do good. Similarly, D&G's history of controversies have led it to a steady decline in brand perception.

Louis Vuitton has managed risk very well and avoided large controversies by constantly assessing public sentiment and proactively pulling from its collection when it might be deemed insensitive.

For each brand, viewer focus on the fashion shows varies. Sometimes it was about the collection itself, but sometimes it was about the people involved or even the production. Part of this may be inherent differences between the fanbase for each brand, so it'd be interesting to further analyze the shows for each of these companies.

A key part of a luxury brand is its heritage. However, with changing consumer tastes luxury brands must continue to adapt to stay relevant. Collaborations with younger popular brands can be mutually beneficial. Street-wear can be made high-end, and such partnerships won't necessarily dilute brand image or associations.
