A lot of people shy away from navy as they think you get a better use of black but I have to differ. I find navy more edgy and even though it is a dark color, it's not as heavy. It's a neutral that can go with almost everything.
To make them summer appropriate, I am going to follow a design rule I learned long time ago. When in doubt, follow nature's color palette. The grounds are the darkest, the trees are lighter, and the skies the lightest. I tied this powder pink shirt to create that illusion.
