This project deals with the potential interaction design that can create ways for fast-fashion consumers toward using second-hand clothing. Through contextual inquiries, main insights were used to guide the prototyping. This led to creating Vintage Block, an app and in-store experience consisting of three different ideas. The first one is a raffle that inspires more people to give quality items to the store for a chance to win the monthly premium item. This is in hopes of receiving a wider variety of sizes and styles from the customers. Secondly, the use of upcycling to customize through the app as well as through QR codes on items at the store. That aims to incentivize customers to download the app and potentially fulfill their shopping needs. Thirdly, an online shopping experience through the app where there is no shipping option to promote sustainable behavior and lower transportation emissions.
