AI-Powered Style: Julia Dietmar on How OpenWardrobe is Solving Fast Fashion with Closet Optimization and Sustainable Tech

The Intersection of Style and Intelligence

At Performix, we believe AI isn’t just for enterprise data—it’s a tool for solving human problems. In this episode, we sit down with Julia Dietmar, a retail-tech veteran and Co-founder of OpenWardrobe, to discuss how her platform uses advanced AI to tackle one of the world’s most wasteful industries: Fast Fashion.

Julia shares her journey from retail software to building an “intelligent ecosystem” that helps users digitize their closets, rediscover forgotten favorites, and make more mindful, climate-friendly purchases.

Key Highlights from the Conversation

  • Your Wardrobe as an Ecosystem: How OpenWardrobe moves beyond “just another app” to create a circular economy through repairs, resale, and smarter styling.

  • The Power of AI Personal Styling: Discover how “Lola” (OpenWardrobe’s AI) analyzes millions of data points to suggest outfits tailored to your unique style and body shape.

  • Solving the Data Quality Gap: Julia discusses the technical challenge of processing user-generated photos (often poor lighting or angles) and turning them into actionable fashion data.

  • Mindful Consumption: How a simple browser extension can prevent impulse buys by showing you exactly how a new item fits with what you already own.

“Innovation doesn’t always mean buying something new. True innovation in fashion means maximizing the value of what we already own through the power of intelligence.”Julia Dietmar


Technical Deep Dive: AI in Fashion

For our fellow developers and tech leaders, Julia explains the complexity of building a platform where products lack unique identifiers. Unlike books (ISBN) or electronics, a white t-shirt has no universal code. Performix and OpenWardrobe discuss:

  • Attribute Extraction: Identifying sleeve length, fabric, and style from consumer photos.

  • Personalization Engines: Moving from generic recommendations to hyper-personalized “digital twins” of your closet.

  • Post-Purchase Engagement: Why brands are now using AI to provide care instructions and styling tips long after the sale.
