I love these Purple Fun and Floral Ballet Flats from Mixx. The name pretty much says it all; purple and fun are the key ingredients of my lust for them.
The thing about patterned flats is that you can actually wear them with a lot more than you think. Mixing patterns is fine to do, as long as the patterns are within the same color family.
But if you're wary of that, I could see wearing these flats with a fab plum wrap dress for going out, or a pair of dark-wash jeans for the weekend. The possibilities are endless.
The best part? Each pair is only about $25!
