⚠️ Sizing Tips (Read Before Ordering)
- This is a standard slim fit, not relaxed. If you prefer looser wear or your chest/waist falls between sizes, we strongly recommend sizing up.
- A bilingual size chart (inches + cm) is included. For best results, measure your actual chest circumference with a soft tape measure — then match to our chart.

📏 Detailed Size Chart (Measurements: Inches / Centimeters)
💡 Pro Tip: All measurements are taken flat on garment — ±1 cm tolerance is normal. Prioritize your body’s actual measurements over standard US sizing.
