When mixing prints and patterns together, there's one general rule i start the process off with; use complementing colors, such as a monochrome or neutral palette. Once you have your color situation sorted out, play with some layering to add the finishing style to the look. Can you use one of the pieces as a wrap around, what can you do with your jeans + shoes to add interest. What type of jacket would pull the look together, a leather moto, a bomber, a jean jacket, and how can you wear that jacket to add even more interest.
No matter how you play around or mix and match, just keep in mind the most important rule. There are no rules. Style is what you can make of it, and how you feel in it. Style brings out the most beautiful you.
Rock on, you. And like always, shop similar looks below.
