1. Understanding FitCheck as one connected experience

FitCheck is designed as a super-app consisting of four independent but interconnected services: Virtual Wardrobe, Outfit Designer, Marketplace, and Outfit Sharing.

Instead of designing each service in isolation, we created an ecosystem map to understand how users, data, and actions could move across the entire platform.

The goal was to ensure that each service could provide value independently, while also creating meaningful cross-service journeys that would not be possible in a standalone fashion app.

2. Mapping the Four Core Services

Virtual Wardrobe

Acts as the foundation of the ecosystem by storing and managing the user's clothing items. Wardrobe data can later support outfit creation, virtual try-on, marketplace listings, and personalized recommendations.

FitCheck Marketplace

Extends the lifecycle of clothing by allowing users to discover, purchase, and resell items, while connecting product discovery with styling guidance and virtual try-on.

Outfit Designer

Transforms wardrobe items into practical outfits through manual creation and AI-assisted suggestions, while also supporting contextual tasks such as travel packing and outfit planning.

Outfit Sharing

Forms the social expression layer of FitCheck, allowing users to discover inspiration, share outfits, interact with others, and turn shared looks into outfits using their own wardrobe.

3. Designing Connections, Not Just Features

The value of FitCheck does not come from placing four services in one app. It comes from allowing data and actions to move between them.

Wardrobe → Outfit Designer

Clothes already stored in the Virtual Wardrobe can be directly reused when manually building or generating outfits, reducing repeated input.

Wardrobe → Marketplace

An existing wardrobe item can be converted into a marketplace listing, allowing users to move naturally from ownership to resale.

Marketplace → Wardrobe

Purchased items can become part of the user's wardrobe, allowing the ecosystem to continuously update instead of treating shopping as an isolated transaction.

Outfit Sharing → Outfit Designer

A shared outfit can become actionable inspiration through “Recreate This Look”, where FitCheck compares the look with the user's wardrobe and suggests matching or alternative items.

4. From Independent Services to a Shared Ecosystem

The ecosystem map also helped us identify which capabilities should not belong to only one service.

For example:
