Good luck, the dimensions all go very well, even the color closes well without staying or tightening the neck. For a French size 42 or 43 men, the color fits well, it is the XXL model that fits busts 118 to 122cm and shoulder width from 48 to 52cm. On the white shirt, the black straightened one just highlights what needs to be done and remains discreet. For a French buyer, don't worry, it's not ecclesiastical at all, it's just stylish, that's all. The buttons are quite large but dyed in white in the mass, they get forgotten on the white shirt. The narrow collar is high, just what is needed to avoid making 'Iran shirt'! There aren't many like these in the catalog, to change and change yourself, buy one! In white, she throws it away!
