Black outfit, the black and white stripes on the bottom of the jacket allow you to blend in the colour with a belt if you want. It is apart of the spring/summer 15′ range in supreme. Much suited in the summer as the jacket is not very heavy yet classy as usual from Supreme.

To combine with the jacket, there is black ripped at the knee jeans from Topman
There are many options for the belt but i have gone with a military belt from HUF
