The Giyin App allows users to build their digital wardrobe. It allows people to easily and quickly decide which of the clothes in their wardrobe they can wear on a daily basis according to the weather conditions. This saves time and energy. In addition, users can create categories and access their closets in an organized and collective way thanks to the information they include when uploading clothes to their digital closets. In this way, they are made aware of the clothes that are not used or preferred, and they receive suggestions that they can donate these clothes to those in need or sell them to generate income. It is aimed to provide awareness and action to prevent excessive and unnecessary consumption of clothes.
