Horizontal Stripes. A Do or a Dont?

So, this is something that I am always finding myself battling with. I love the look of bold horizontal stripes in bold colors. I find that when wearing them I have the tendency to look wider than I am. That is until I found this amazing cardigan, it has the bold colors and the bold stripes, the magic that makes it work is that it has black in a bolder stripe then the colors. LOVES IT!
