Choose the Right Bos-Japie Fit
Check the fit before checkout — especially for bulk orders, gifts, and custom apparel.
How to Measure
Lay a T-shirt that fits well flat on a table. Measure straight across the chest from underarm to underarm. That half-chest measurement (in centimetres) is what the tables below show.
Product cuts can differ slightly by garment supplier and colour. For bulk or team orders, send us the size mix and we will help check it before payment.
