Can’t help myself when I see a match between two prints. And I do see this often.
It can be a match on the colors, on the patterns, anything really. It is kind of subjective, an intuition I’d say. But to mix prints is more like a feeling and a state of mind than a planned or ruled action. So, let your imagination guide you in the task of mixing prints in your wardrobe and play around.
The whole point when dressing up is to have fun and to follow your mood. So, just go with the flow and start matching up and dressing up.
