See bottom of post for update.
Lanvin's festive pom-pom sandals retail for $540 at Barneys.
These sandals by Bamboo at Lulu's have their differences, but they definitely remind me of the Lanvin version above (maybe a little less puff in the pom-pom?). They retail for $20 and you can click here if you're interested in purchasing (also available in blue).
Go Jane also has a version that comes in black, red, blue, and raspberry for $17.50. Click here to purchase.
*Update - 8/12/10* - The always amazing Budget Babe actually found these Dollhouse sandals but I wanted to share them with my readers as well. This amazing look 4 less retails for $31.25 and they come in a ton of other colors. Click on the photo below if you're interested in purchasing.
