For clothing, provide detailed size comparison guidance (including fit analysis for different versions), fabric characteristic explanations (such as breathability, wrinkle resistance, skin-friendliness) and seasonal styling advice; for jewelry, popularize material differences (925 silver, freshwater pearls, etc.), authenticity identification points, scenario-based matching plans (commuting/banquet/daily), and offer 1v1 exclusive recommendations based on users’ height, style preferences and usage scenarios, helping users quickly lock in suitable products and avoid return troubles caused by improper selection.
