I always find it difficult to come up with something to wear when it's really hot outside #1 because I really only wear jeans and #2 because I only wear dark colors.  But after spending slightly too long thinking about it, I came up with this outfit and I think I did ok.  The light shoes and shirt work well with the native style fabric in the shorts and a pop of color from the sunglasses.  Most importantly, I was able to stay pretty cool on a humid NYC day.
