My decision rule works like this:

Objective

To minimise attire decision fatigue

Outcomes

Get attire that:

• maximises mobility, thermal comfort, decency and accessibility

• minimises cost and components

Nike techfleece jumper + Chanel (yes, men's) dress pant + Nike Runners for casual wear and any kind of formal dress shoes cause they're all bad for your feet, bad for running, and not that great looking anyway + Uniqlo Collared shirt switched for a tshirt when sleeping and another tshirt to wear underneath to keep the sweat away, or a stripped down combination of that, appears to be the most versatile, minimal, comfortable, warm but mobile and professional mix I can find. I've convinced many people in my city to go with that combo somehow.
