Chanel and Christian Louboutin are most popular fashion brands on Pinterest
Chanel ranks in at #1 fashion brand on Pinterest.... with 150,000 total shares, 58 million total impressions, average of 56 pins per day, and an average of 1,244 repins per day. All of this, and Chanel does not even have its own Pinterest page.
Top image sources stemmed from the brand's own webpage, and therefore certain brand's websites, like Manolo Blahnik, did not rank very high since there were not many "pinable" images.
