Social media in the fashion industry: Social media use in the fashion industry has enabled average consumers and regular people to have much more interaction with fashion designers and high-end clothing, shoes and accessory firms.  Unlike traditional advertising platforms, such as billboard ads, magazine ads and television commercials, which the fashion company and their advertising agency had complete control over, when fashion companies do a social media marketing campaign in the 2010s, average consumers and regular people can post online comments immediately below the fashion company's social media advertisement.  This accessibility is due to the increased usage of social media since 2009.  Social media is a real time platform that reaches across the globe; this has had a great impact on how consumers interact with the fashion industry.  Social media has brought about new channels of advertising for fashion houses to reach their target markets.

Social media users participate in the hashtag campaign by posting photographs of themselves holding up signs displaying the hashtag and by including a short message about why they are participating.

On September 11, 2014, the BBC aired a segment on the campaign which resulted in international coverage.  As of March 2016, the petition on Change.org has received over 300,000 signatures.
