Accordion pleats are popping up all over the place for Spring and Summer 2012, and it's not just on the runway. I have been seeing the pleat trend on models, celebrities, and, of course, on one of my most favorite style icons—Kate Middleton. 

There are so many great ways to wear pleats this season—skirts, dresses, sweaters, tops, even purses.

And I'm pretty sure I have all of them on my wish list.
