the newest style on the market as soon as possible. They emphasize optimizing certain aspects of the supply chain for the trends to be designed and manufactured quickly and inexpensively and allow the mainstream consumer to buy current clothing styles at a lower price. This philosophy of quick manufacturing at an affordable price is used in large retailers such as SHEIN, H&M, Zara, C&A, Peacocks, Primark, ASOS, Forever 21, and Uniqlo.

The advancement of technology has allowed fast fashion to gain popularity over the last decade. Technology has allowed designers to create specifically what their consumers want according to what is "in" at the given moment. Every month there are new things trending and new things being displayed in stores to market towards the youth. Technology has the power to change all the issues within the fast fashion industry. Brands such as Zara have
