What do you wear at home, loose or tight fitting clothes?
Most say “loose”. It’s healthier. It gives you space to breathe. Your etheric body circulates its energy unrestrained. We’re relieved to take off our suits when we arrive home.
Jesus worse loose clothing. Buddha wore loose clothing. Have you ever seen a movie villain wear anything other than tight clothing?

Tight fitting clothes aren’t “bad”, they serve a different purpose, but feeling free isn’t among those. The constraint of tight clothing makes you more focused and disciplined. At a job interview you’re not likely to show up in loose jogging pants and hoodie (unless you’re an American). You convey that you’ve reined in your Ego for the mission.

Wearing pyjamas at a supermarket is a sign of laziness. A person dressed “smart” and “tight” is more likely to be ready for action and tends to be more orderly.
You can find a balance between tight and loose. There are loose fitting suits, which were more common in the 1920s and 1930s – formal, but still comfortable.
Some clothing is so damn tight, we feel uncomfortable just looking at it (image upper left side). Some gym leggings are so tight, they constrict blood flow and breathing – unhealthy for workout. Overuse of loose clothing is often used to cover up overweight rather than feel free. On the other hand, it’s a mystery to me why so many overweight people use tight clothing.
Tight shirts are often used to emphasize breasts or muscles rather than for stronger focus.
I don’t like rigid rules, but if I were to voice a general rule, I’d say “prefer slightly more loose clothing, except for formal occassions”.
Clothes are an extension of you. Question how clothes make you feel and what purpose different types of clothing serve. Is there a way you’d like to feel? A way you’d like to be treated? A way you’d like to live? Then dress that way. What you attract into your life corresponds to who you are and who you are is partially defined by what you wear.
