This project explores the concept of a second-hand clothing platform where users can buy and sell pre-owned apparel. It is a personal iOS app concept developed through a comprehensive UX research process, from problem discovery to usability testing.

It’s time to make fashion

It’s time to make fashion
good for people and the planet

The fashion industry is currently one of the world’s largest consumers of natural resources. Producing new clothing requires vast amounts of water, energy, materials, and land, placing a significant burden on the environment.

It is my goal to design a buy-and-sell second-hand clothing app that will help protect the planet and change the fashion industry for the better. Choosing to wear sustainable fashion helps consumers break the vicious cycle of fast fashion trends.
