📏 Precision Sizing Matrix (头围尺码测量指南):
⚠️ HOW TO MEASURE (测量方法): Wrap a soft measuring tape about 3cm above your eyebrows and around the widest part of the back of your head. Take one snug measurement and one slightly loose measurement, then find the average.
FIT NOTE: If you prefer a more comfortable/relaxed fit, or if you have a wider facial structure (chubbier cheeks), we highly recommend sizing up by ONE size.
