Thakoon's Spring 2010 show had these floral mixes that I thought were really pretty and just worked very well.

You don't even need to try with this dress, the mixing is already done for you!
I like the bold flower amidst the stripes.
And a pretty pastel frock.
Some outfit choices:
This pretty dotted blouse +
this plaid mini is a great mix of patterns.
I would add this blazer and these platform pumps to tone down yet not take away from the patterns.
Adore this polka dot, ruffle number +
this gorgeous striped embellished cardigan.
Add these cutie shoes for a perfectly mixed matched outfit!
This comfy long cardigan just needs an embellished tee +
this little plaid skirt. Comfy and Cute!
Complete the look with these gray flats.
