Agile, Collaborative Design & Simulation for Physical & Digital Fashion

The Problem

Current industry players still use old code bases to power their software. These software programs do not connect their production patterns to their 3D environment. Others provide a platform for virtual fashion design, but those designs are not usable in games, films, apps, or other spaces in the virtual fashion metaverse. Users of these programs must use up to seven different software programs to create the required physical and digital end products for each garment design they create.

Seamly is Different

Seamly quickly and easily empowers any size fashion business to transform its business model, to start generating higher profits, while also providing access to the virtual fashion and gaming skins market to expand the visibility of their brands and create new revenue streams. Seamly is easy to use and affordable!
