Victoria’s Secret knows the youths love messaging apps. So, instead of marketing on popular platforms like Snapchat or Kiik, it made its own. The lingerie retailer has rolled out a mobile chat feature on it’s shopping app, Pink, that lets shoppers participate in public message boards that have predetermined topics. Users can also customize their background colors and use branded emoticons. The big draw, however, is that the messenger will be rolling out exclusive content during the Victoria’s Secret Fashion Show on Dec. 9.
