How do I build a size chart and fit guide that actually cuts returns for my fashion brand?

Indian apparel returns run brutally high on sizing alone because there's no universal standard - an 'M' at one brand can sit 4-6cm off an 'M' at another - so a bare S/M/L label is close to useless; publish real garment and body measurements in cm/inches next to the variant picker, not three scrolls down. Layer on a short fit-finder quiz (height, weight, usual size in other brands): AI-driven size recommenders report meaningfully fewer size-driven returns and a conversion lift when shoppers get a confident recommendation instead of guessing (numbers vary by category, treat as directional). Put the size chart link right beside the size selector, never buried in the description tab.
