Why is there 2 more pieces on a shirt in a row of buttons, and one of them is a different size?
Answer from: Nikita A.:
Priest of the Russian Orthodox Church, Archpriest...
This is a spare button. And men's shirts if you have not noticed there are 4 buttons smaller than those on the front placket. Two buttons on the collar, two buttons on the placket can sleeves. That's why they sew two buttons on the shirt.
