I read somewhere that ties cover up the buttons on a shirt. So while uncomfortable, silly-looking, and a tool for strangulation, they serve a purpose. Jackets, on the other hand, are completely absurd. With the lapels turned outside by the cut, they provide zero warmth in cold weather since they do not cover the chest area. They also are hot in warm weather. Impractical and silly-looking, the worst of all worlds.
Still less silly than sweatpants and slippers.
Glad to know you only wear a potato sack. Do you spend the absolute minimum on clothes, or do you replace your t-shirt when it gets a permanent mustard stain on it?
