I grew up with the belief that blue and green should never be seen but over the years I've discovered that that does not include navy nor khaki. In the past I've worn navy and lime and navy and grass green and khaki with turquoise
This must mean that both navy and khaki are neutrals. What better to put these two neutrals together so last weekend I wore navy and khaki. I've since seen navy and khaki on people in the realsphere so its a common combination, which goes to show how out of touch I am.
Anyway, try it, you'll see how well it works. This week's challenge for you.
