In a breakthrough for luxury fashion e-commerce, Joyabuy
The Science Behind Perfect Fit
Joyabuy's custom-developed algorithm processes three key measurements:
- Shoulder width (measured between acromion points)
- Height/torso length ratio
- Carrying position preference (shoulder vs cross-body)
The system then cross-references these inputs against its continuously updated comfort database, which includes feedback from over 12,000 Dior Saddle Bag wearers worldwide. Machine learning identifies subtle patterns between body proportions and optimal chain length configurations that human fitters might overlook.
Virtual Try-On Innovation
Prior to purchase, customers receive:
- Personalized chain adjustment recommendations (to the nearest 0.5cm)
