There is a need for formal and business wear in life. But as much clothing as possible should pass "The Dinghy Test."
The rules are simple. Can the clothes you wear enable you - even encourage you - to successfully get in and out of a dinghy? Can they allow the range of motions required? Can your shoes provide traction? Can the clothes recover gracefully from less than successful attempts of entrance, egress or transport?
For example, this means no "dry clean only" garments. Every garment should be able to withstand washing; by hand if necessary, machine washing preferably.
In ability and temperament, we become more like the clothes we choose to wear. So it makes sense to choose authentic garments that represent both who we are and who we want to be.
