Digital Product Passports (DPP)
The EU Digital Product Passport regulation, part of the Ecodesign for Sustainable Products Regulation (ESPR), will require fashion brands to provide detailed product information including materials, manufacturing origin, care instructions, repairability, and end-of-life recycling options. The Commission's ESPR working plan lists textiles and apparel as a priority group, with the rules for them targeted for adoption around 2027. Textile DPP requirements are not yet in force, and the exact compliance date depends on the delegated act, so some brands are preparing early.
What a DPP Contains
- Materials and composition: Full bill of materials with origin traceability
- Manufacturing details: Factory location, production date, quality certifications
- Sustainability data: Carbon footprint, water usage, chemical usage
- Care and repair: Washing instructions, repair guides, authorized repair centers
- End-of-life: Recycling instructions, material recovery guidance
- Authenticity: Serial number, anti-counterfeiting verification
Technical Architecture for DPP
Data Storage:
- Optional blockchain anchoring of product records for tamper-evident provenance
- QR code or NFC tag on physical product linking to digital passport
- Centralized database for brand-controlled data, decentralized anchoring for verification
Integration Points:
- PLM (Product Lifecycle Management) system for design and materials data
- ERP system for manufacturing and quality data
- Supply chain management platform for logistics and traceability
- Consumer-facing app or web interface for passport access
Development cost: €80,000-€200,000 for a DPP platform, or €30,000-€70,000 for integration with an existing traceability platform that offers DPP support (for example Retraced; check what each vendor, including TextileGenesis and Provenance, supports before you commit).
Supply Chain Digitization
Fashion supply chains are among the world's most complex, spanning multiple countries and dozens of suppliers for a single garment. Digitizing this supply chain is both an efficiency play and increasingly a regulatory requirement.
Supply Chain Platform Features

| Content Generation | LLM-based product descriptions | €20,000-€60,000 |
Visual Search Implementation
Visual search allows users to upload a photo (from their camera, social media, or the web) and find visually similar products in your catalog. Pinterest offers visual search through Pinterest Lens, and many fashion retailers have added similar features.
Technology stack:
- Image preprocessing (background removal, color normalization)
- Feature extraction (ResNet, EfficientNet, or ViT)
- Vector similarity search (Pinecone, Milvus, or Weaviate)
- Result ranking with behavioral signals
Development cost: €50,000-€120,000 including model training, API development, and UI integration.
Social Commerce Integration
Social commerce, buying directly within social media platforms, is transforming how fashion is discovered and purchased. Instagram and Facebook Shops now send buyers to the merchant's own website to check out, because Meta phased out onsite checkout in 2025. TikTok Shop availability depends on the country, so check the markets you sell in.

Frequently asked questions
- How much does a fashion-tech app cost?
- Costs range from about €60,000 for a basic fashion e-commerce app to €450,000 or more for a full luxury platform with AR try-on, AI personalization, and clienteling. Typical ranges: luxury e-commerce €180K-€450K, virtual try-on €60K-€280K, fashion marketplace €120K-€280K, supply chain platform €150K-€400K.
- Should I build a native app or a web-based platform?
- Both matter. A web platform captures search traffic and reaches everyone, while a native app delivers richer AR and push notifications. Many fashion-tech companies launch on the web first, then add a native app.
- How does the EU Digital Product Passport affect development?
- A product passport must be reachable through a data carrier such as a QR code. Development work includes data collection across your supply chain, a consumer-facing view, and links to certification data. Budget €30,000-€70,000 with an existing traceability platform, or €80,000-€200,000 for a custom build. The textile rules are not in force yet; the Commission's working plan points to 2027.
- Is AR try-on worth the investment?
- It can be, but the return depends on your products, return rate, and traffic. Run a small pilot, such as a web-based try-on for one best-selling category, and measure conversion and returns before a full build.
- Which AR tools are used for virtual try-on?
- ARKit and RealityKit on iOS, ARCore on Android, MediaPipe for cross-platform face, hand, and body tracking, and Snap Lens Studio for social lenses.
