You’re absolutely correct about contextual intent but we do use this as a guideline for our dress and conduct
To dress to draw attention to yourself in the house of God should never be done
If you wouldn’t act or talk in a particular way in the house of God neither should you do it outside the house of God
Correct, I think we're on the same page...
Short Version: It's not really important what you wear to church (within reason, obviously) as long as you're there to worship and not trying to draw attention to yourself instead of God
