One of my favorite scarves is this skull print I found at Zara. It's fun, it's cool, it's trendy, and it was cheap...fashion success!
The best way to work any type of skull print into your outfit is to keep the other items plain or neutral. You want the print to be the focal point. You can definitely work color into the outfit, but don't let it distract from the print. I like wearing my scarf over a boyfriend blazer with flared jeans and a boot. Easy and chic....and not goth or juvenile.
