This is the first fashion week in New York since the death of Bill Cunningham, the originator of street photography. However, as long as you are careful, you will still see his commuting style-blue jacket in various shows. On the first day of the show, more than 70 photographers wore uniforms and uniforms to take photos.

As Catherine Bennett, general manager of Fashion Week organizer IMG, said, although the old man is no longer here, he still affects New York day and night. Over the past four decades, the blue coat has become Bill Cunningham's signature feature. Only on rainy days, he would change into a blue raincoat and ride on the street astride his bicycle. The shooting targets include fashion leaders such as Anna Wintour, the editor-in-chief of American VOGUE, as well as small traders.

As his reputation grew, the origin of this work clothes also surfaced: In his early years, Bill Cunningham discovered it in a hardware store in Paris. The tags cost $20 and are typical working-class clothing. But after trying it on, he found that it was unexpectedly easy to wear. There were several spacious pockets on the clothes that were enough to store spare papers.

Of course, the blue jackets commemorating the photographers at New York Fashion Week this season are not made in France. They are jointly manufactured by IMG and interior product design group Villency Design Group.

Just last month, the NewportFILM film festival screened the 2011 film "Bill Cunningham New York." This ten-year-old film can be called the most comprehensive film and television documentation of Bill Cunningham. All guests attending the movie must wear blue to commemorate this fashion street photography master.

The fashion industry's tribute model doesn't stop at styling. With the petition of his former friends Nick Nicholson, Derek Blasberg, Nina Garcia and others, the New York City government approved the naming of the intersection of Fifth Avenue and 57th Street after Bill Cunningham - this is where he spent many years looking for shooting targets.

50 seats recently appeared in Bryant Park. They are arranged in the shape of a 35mm camera, and the backrests are made of fabric similar to the Blue Jacket machine. Each chair comes with a photo of Bill Cunningham at work. This was once one of his most frequent working locations, and the Lowell Fountain in winter and summer constituted an important setting for his street photography.
