The Challenge
FashionPass disrupts the traditional fashion industry with a subscription-based clothing rental model — members rent clothes, wear them, and send them back for new items. The platform needed to handle:
- Complex subscription tiers with different item limits and access levels
- Real-time inventory management tracking thousands of garments across multiple locations
- Automated logistics — shipping, returns, cleaning cycles, and restocking
- Personalized recommendations based on member preferences and browsing history
- High-traffic handling during sales events and new collection drops
The previous system couldn't scale with growing membership demand, causing inventory sync issues and poor user experience during peak traffic.
