You may recall this coat from my haircut reveal post here. I'm wearing it in the same way with this outfit, playing off the blue and black pattern by wearing a cobalt dress over black tights and boots. It can be tricky to outfit around a statement piece like this coat. A good rule of thumb is to let the statement garment be the star keeping the rest of the outfit simple/neutral. Another approach, which is the one I'm employing here, is dressing to match or coordinate with the standout piece. A third route, and one that only a experienced outfitter should attempt, is to pair the statement piece with OTHER statement garments for an overall out-loud look. If successful that would certainly be badass.
