Mixing and Matching Prints Together with Style?

I wore this burgundy print dress out to dinner the other night and because I was in such a rush I totally forgot a wrap or jacket to ward off chilly Socal night. As default, I had to make do with a print wrap that was in the car. (*Darn it!) All night, I felt as if I committed unspeakable fashion crime by mixing prints. I would gladly go without the wrap but freezing to death was not very savvy or wise. I had to compromise and pretended I got dress in the dark.

What I Am Wearing:

-BGBG burgundy wrap print dress
-Vintage ostrich clutch --- Thanks to Savvy Mom
-Beige Tod's heels --- Not shown but many of you know this is one of my favorite pairs already.

Anyhoo, even though I was not happy with print overdose the other night, mixing right prints together is quite savvy. Normally I will pair a print piece with a solid piece so there won't be an explosion of contrasting prints (ie. a floral top with jeans or solid color bottoms). However, the adventurous me wants to do something different, perhaps with more flair. SO, I turn to BFF Michelle, the super image consultant, for some tips:

So when mixing multiple prints make sure that at least the colors match. Ideally, prints are most harmonious to the eye when one is larger than the other. So don’t be afraid of mixing herringbone with plaid because they can be fun. But floral and plaid, maybe not so much… because the last thing we want is for someone to make fun of our prints like in “Ugly Betty”....

I have learned I should mix prints from the same color family and avoid mixing patterns that are too different in size. It is savvy to mix small with medium or medium with large. However mixing large patterns with small patterns won't be as easy on the eyes. Hopefully in the near future I will be able to put together stylish multi-pattern outfits to share. How do you mix and match different print elements together?
