Here is the thing:
Okay so for whatever reason you DIDN’T wear you jacket and/or hat by davening as required per mishna brura. Nu. 99.9+% of the time no one is going to come over to you and critique you, even though mishna brura says you should be wearing it.
BUT DON’T GO AROUND, ON BLOGS OR ELSEWHERE, PROMOTING (OR OKAY’ING) THE IDEA OF NOT WEARING A JACKET AND/OR HAT! DON’T SPREAD WHATS WRONG.
