Hello,
I think whatever opengraph plugin you are using on your pages might be causing the issue. Take a look at: https://search.google.com/structured-data/testing-tool/u/0/#url=http%3A%2F%2Fwww.lulus.com%2Fcategories%2F13%2Fdresses.html
On a semi-related note, your og:image tag is missing 'og:image:width' and 'og:image:height'.
