Rules for single-button, single-breasted suit

#TeachingsTuesdays

Hi men out there, learn the basic buttoning rules with us!
A single-button, single-breasted suit is an evening suit that’s quite longer than usual suits and has only one front button. As a rule, you have to fasten the only button on the blazer when standing. When sitting for dinner, you can unbutton them. 

Well, unlike other blazers with two or more buttons, you don’t have a choice about whether to fasten the first or last button.
