I'm not entirely sure when the idea started that you shouldn't wear horizontal stripes unless you are Audrey Hepburn's body double but, it was first brought to my attention by Stacy and Clinton. You know who I'm talking about. That show on TLC that took unsuspecting fashion victims and taught them how to style themselves. I fully admit that I loved that show and avoided horizontal stripes for years per the gospel of Stacy and Clinton. But, as we've ushered in an age of "do whatever the eff you want no matter what kind of a body you have," I've learned that stripes are just another rule to be broken. Not wearing horizontal stripes is for fashion beginners and once you start to get an eye for proportions, it becomes evident that stripes are just like everything else clothing wise. They are not all created equal and some will flatter and some will not. Don't blame all the stripes for the crimes of some, yo! And for really advanced dressing, chuck flattering out the window. Put things on your body that make you happy because you have no obligation to fit into anyone's definition of appealing.
If stripes make you happy, rock it out.
