Stussy Basic Pullover Hoodie Size Medium Charcoal Gray with a hint of Navy Blue. A Navy Blue-ish Gray: Periwinkle.
At first look I thought this was black. Then I looked in natural light outdoors and it is a charcoal gray-ish with a hint of navy blue. I believe the color is called Periwinkle. Will go with Black, Gray or Blue. 
Excellent quality sweatshirt. 
Gently used and well taken care of. Please view all photos :-)
