The Brazilian retailer C & A will be using Facebook to show how popular certain items of clothing are. It works by using Facebook Likes from the retailers own Facebook page. But in this case, they are calling it Fashion Likes! It has to be assumed that the retailer will only be showing popular items and not the ones with Dislike on!
According to the C & A announcement this is how the fashion like works;
We decided to offer our consumers help from a giant network of people. We put the clothes of the new collection on Facebook. There, users could click on LIKE for the items they liked more. These LIKES were added up in real time on the hangers of the actual piece of clothing in the store, helping thousands of women in the difficult mission of choosing the ideal clothes.
