Hi Zahavasdad.
Individualism is encouraged. In fact, I find that there is room for every type of person to be accepted in the community.
Specifically, you are talking about clothing. So to generalize that “individualism is not accepted” is too broad a statement, in my opinion.
You can dress as an individual or you can dress with according to the preferred customs of any given community.
If you conform to a dress code, unless you are a fashionista, that does not mean you have lost your individualism.
If you follow sports, do you like your team to come onto the field or court in the same uniform? It shows a solidarity and makes a statement separating you from the rest, even though others are doing as you do.
I would not sweat a sense of losing your individuality because of a preferred manner of dress. You are still you and there is no one like you.
