I rarely change from loungin shorts and a sleeveless shirt unless I need to go out, then I either put on some jeans or cargo shorts and tennis shoes. one of the many advantages of working from home.
Suit every day. Brooks Brothers or Vineyard Vines tie. I cannot imagine feeling as prole as the rest of you people.
Which day? Sunday - Suit and tie (sport coat and slacks or jeans in the evening), dress shoes Monday - off, jean shorts and tee, Reeboks Tuesday - Button up shirt, jeans or khakis. tan Doc's or Reeboks (solid black ones) Wednesday - " Thursday - " Friday - Khaki shorts, polo, or nice t-shirt. tennies that match my shirt (yes, I coordinate) Saturday - jean shorts and tee, Nike court shoes, tennies, or sandals (no socks!!) Any moment not in a suit (24/7) could be changed with a phone call, or to at least wearing a sport coat and khakis or nice jeans... But most days I can casual it out.
Kaki pants and short sleeve polo/golf-type shirts. I have a 5-day rotation of shirts and pants. I have a few "backups" just in case. My wife incessantly makes fun of me for this, but I'm sorry -- I'm not trying to make a fashion statement. It's work, who the hell cares?
