It's Casual Friday in the office.

[The Swagman]

Casual Friday is an American and Canadian custom which has spread to other parts of the world, wherein some offices celebrate a semi-reprieve from the constrictions of a formal dress code. Whereas, during the rest of the week, dresses, stockings, business shirts, suits, ties, trousers, and dress shoes are the norm, on Casual Friday workers are allowed to wear more casual dress. Some companies allow jeans, T-shirts, hoodies, and sneakers but others require smart casual dress. Some offices have a themed dress down day, or encourage people to wear very casual clothes. On this day, even managers are allowed to dress down.

Claims that the guys in the office are finding it hard to concentrate on these days is a myth.
