When working from home it means you can enjoy a certain degree of freedom, and the same applies to your outfit. When choosing what to wear, one should remember that the choice of clothing has an impact on the quality of your work. “ You look good, You feel good , You do good”
What kind of outfit would be appropriate, The kind of outfit that would be OK to be worn on "Casual Friday", an overall more informal style. On the top- a good business style shirt, something like a plain / small patterned shirt or even a collared t-shirt. These are usually a good choice as it is easy to pair/match. On the bottom- a comfortable pair of modern fitting “Stretch chinos” / a flat front trouser ( something with a natural stretch) / even a pair of dark stretch jeans.
Why the emphasis on “stretch”. For one simple reason, stretch fabric’s offer the most amount of comfort. Which is a requirement, especially when you are seated at a desk for most part of the day.
