I bought an Asian XL, too small for me even though the size said 104 cm chest wich is normally my size. Despite the size, good quality. I will order an XXL now.
Nice t-shirt, the fabric is high quality, but sewing would deserve more attention (see photo). This is an Asian slim cut, so measure your size across the chest and add 10 cm. The look at the size table. If you have larger muscles, armholes may be too narrow after all.
