One of my favorite things to pair together for an outfit is different patterns. Mix and matching various patterns seems a little outlandish, I know, but it actually is a brilliant way to take your style to the next level because it adds a more unique fashion.
Number one rule to accomplish this look is to make sure the items you are trying to pair have at least one color in common. For example, in this picture I put together this flowered pattern top with the navy striped skirt, but it looks super cute because they both have white and blue as the colors in common!
I encourage you to try this technique out, I promise you will enjoy and have fun coming up with adorable and unique outfits!
