FAQs
AI fit vs simple size chart?
Size chart = static reference. AI fit = personalized recommendation. Both useful — chart for confidence-checking, AI for the recommendation step. Use both together.
When does AI fit pay off?
Above $50K/mo apparel revenue. Below that, return reduction × app cost ROI is too small. Above that, AI fit cuts returns 35%+ which dwarfs subscription cost.
