Discover and Shop Rare, One-of-a-Kind Fashion & Lifestyle Finds
IFFI is a curated peer-to-peer marketplace app that connects users with unique, rare, and luxury fashion and lifestyle items. Designed for discovery and individuality, IFFI enables shoppers to explore a dynamic catalog of secondhand and exclusive pieces—ranging from vintage gems to modern must-haves—while empowering sellers to share their personal style. Similar to Poshmark but with a focus on exclusivity and standout finds, IFFI blends community with commerce for a fresh, trend-forward shopping experience.
IFFI.app needed a distinct identity and a web and mobile marketplace experience for rare, discontinued, and hard-to-find items. The project focused on clear marketplace messaging, browsing and item discovery, checkout functionality, and a technical foundation for a growing catalog.
What We Built
Harris Digital developed IFFI.app’s brand direction and marketplace messaging, including logo and color guidance. We redesigned the web and app experience with organized navigation, responsive layouts, clearer product categories, and personalized item recommendations.
The development work also included backend infrastructure updates, payment gateway integration, and checkout improvements. These features formed the marketplace’s design and technical scope.
