Today I Learned #4

So we were at a wedding where everyone was in a suit and the men were handed flowers to put in the buttonholes. The notch in my husband’s jacket was sewed closed and he got to wondering why the buttonhole existed in the first place.
Dad goes “have you ever wondered why the lapels are shaped the way they are on a suit jacket?”, the boys replied no. Dad flipped the collar up and overlapped the buttonhole on the other lapel.
Voila! It became a winter coat! The top part of the collar became what we call a sherwani collar, and the V-shaped notch in the lapel design ended up covering the other lapel and that is where a button used to go so the buttonhole could be fastened and closed.
Mind = blown.
