Did New York Mayor's Wife Wear Jeans To Cop's Funeral?

The Daily Mail offers the above photo and the below report:

...within hours of the funeral for Officer Wenjian Liu, pictures began to circulation on NYPD email chains and social media criticizing First Lady Chirlane McCray and were promptly turned into a series of memes, pictured. The criticism reached such a furor that City Hall issued a statement saying that the outfit was in fact a dark pants suit and cost $600 from a designer boutique.
