As much as I'm an introvert and reserved, I tend to take more fashion risks. Mixing prints is one of them.
I know some are hesitant to mix prints, but starting with simple patterns really helps. Polka dots is one of my favorite patterns to mix, but I've started experimenting more with stripes and flowers. I remember being hesitant to do anything bold for fear of what others might think. But as I became older and a bit more comfortable in my skin, I enjoyed the process of putting unique patterns and prints together.
Buzzfeed has a great article on mixing prints, providing great tips for those who may be less comfortable putting different prints and patterns together.
