When I was in a store yesterday the staff remarked that blue blazers were very difficult to match pants with, that in 2016 you could not longer one with chinos because it was too "preppy". This seemed odd to me as I thought it was a foundational garment, even more so because I'd literally bought one the day before. Is a blue blazer still foundational and what would you match a (dark) navy blue blazer with? Maybe light grey pants? I've seen white - I'm definitely not that adventurous. Something like this is still viable?
