3 Button Lapel:
A 3-button suit has a high button stance, creating a shallow “V” and consequently, looks the most “buttoned-up”. Literally. Because it lacks the elongating effect of a 2-button or 1-button suit. The 3-button is also the button type that seems to be most trend-elastic. Commonly considered “old-school” the 3-button is mostly used for a taller, reto and/or older gentleman.
How to wear it: Button the top and middle buttons or just the middle one; never button the bottom one.
Where to wear it: Anywhere other 3-but
