In May of 2016 Instagram completely changed its design making the app page black and white and changing the icon to a more colourful and "modern" design. I think this change was influenced by the fashion trends in 2016. Some trends in 2016 included: chokers, bomber jackets, baseball caps, velvet, and slip dresses. I think because of these trends Instagram wanted to change the aesthetics of the app to match the current fashion trends. The new layout was very neutral and would match future trends. -
