YODY In Life x AR Body Tracking: Try-On Polo Shirts with Ultra-Realistic AR Technology by Marvy

Background & Concept

At the launch event of the “YODY In Life” collection in early April in Ho Chi Minh City, YODY aimed to bring customers an innovative experience that blended modern technology with the youthful, dynamic, and stylish spirit of the collection.

To bring this vision to life, YODY partnered with Marvy – a pioneer in AR Body Tracking technology in Vietnam. Marvy transformed the event’s interactive zone into an impressive “virtual fitting room,” where guests could simply stand in front of an AR mirror, wave their hand, and instantly “try on” three polo shirt designs from the new collection – no real outfit change needed.

Fast – convenient – fun, and perfect for snapping photos, recording videos, and sharing instantly on social media, this AR fitting experience became one of the hottest highlights of the event.

Scope of Work

• App Development: AR Body Tracking features integrated into the AR Mirror application.
• 3D Model Development: Creation and optimization of 3D models of the polo shirts from the “YODY In Life” collection.

AR Body Tracking

AR Body Tracking allows device cameras to detect the shape, proportions, and movements of the human body in real time.

For this project, Marvy has:

• Optimized detection algorithms to ensure precise tracking under various lighting conditions at the event.
• Synced body movements in real time so that each 3D shirt aligned seamlessly with gestures and poses — even when users turned around or raised their arms.
• Reduced latency through on-device image processing, creating a smooth and natural “real-wear” feeling.

Thanks to this technology, customers only needed to stand in front of YODY’s “magic mirror,” select a polo shirt, and immediately “try on” the product virtually. Within seconds, the AR system recognized body movements and synced them with the 3D model for a perfect, life-like fit.

3D Model Development

Starting with YODY’s raw 3D design files, Marvy recreated three polo shirts with high fidelity:

• Accurate proportions to match real-life products.
• Fabric textures optimized to reflect light and colors authentically.
• Detailed finishing on seams, buttons, and collars for a polished look.
   

The three AR Mirror polo shirts included:

• White Polo – Youthful & Casual

• Navy Polo – Elegant & Timeless

• Grey Polo – Minimal & Modern

Process:

1. Developed detailed 3D models for each shirt.
2. Optimized textures, lighting, and reflections to create a vivid effect.
3. Integrated models into the AR Body Tracking system with motion synchronization.

UX/UI & App Experience 

To ensure an easy and engaging user flow, Marvy designed the interface with:

• A visual, eye-catching layout featuring “YODY In Life” branding.
• Large, clear selection buttons for shirt options.
• Playful visual effects: subtle animations that made trying on shirts more fun and interactive.
• Seamless performance: smooth switching between outfits within the app, delivering an uninterrupted experience.

The AR Body Tracking Mirror not only became a tech highlight but also turned into the ultimate check-in hotspot at the event.

• Hundreds of guests tried on and recorded AR shirt experiences.
• At the Hai Duong launch event alone, over 200 attendees enjoyed the AR feature.
• Many KOLs and event guests shared their AR try-on clips with the hashtag #YODYInLife, amplifying the buzz around the collection online.
• Prominent KOCs also joined the trend, boosting the campaign’s visibility.
