Today I am wearing a dark coffee colored (looks almost black), 3-button suit with notch-lapels; a maroon candy stripe shirt with French cuffs; a check silk tie in red/blue/green/beige; a maroon silk pocket square; a pair of black half-brogue oxford shoes; and a vintage and rare Rado Elegance automatic watch in stainless steel.
Following is a note about three button suits. Technically, you can either fasten only the middle, or the first and second buttons of a 3 button suit. However, this choice is actually dictated by the roll of your lapel. In some three button suits, the roll of the lapel extends beyond the first button and it looks almost like a 2-button suit. In these suits, if you fasten the first two buttons, it will look odd because the jacket was designed for only the second (or middle) button to be fastened.
If carefully look at my suit today, you will find that the lapel extends beyond the first button and therefore, I have fastened only the second button. This is how this jacket was cu and intended to be worn. However, if you look at the suit I wore yesterday (which was also 3-button), you will find the lapel ends before the first button and therefore, it would be proper to fasten the first two buttons.
