When someone goes to shul wearing sweatpants and a tee shirt with his favorite rock band logo, it is not a kiddush Hashem.
When someone has sports team logos painted on his kippah, it is not a kiddush Hashem.
When someone walks out in ripped jeans and a messy tee shirt, it is not a kiddush Hashem.
When people wear clothing that leaves much more uncovered than covered, it is not a kiddush Hashem.
A person who walks around with rumpled jeans, would most likely wear a rumpled shirt and pants if he dressed yeshivish. If you compare the two, for davening the white shirt and pants is more appropriate. For cleaning sewers, the jeans are appropriate.
To make rediculous remarks like yours, Mr. Dad, is neither a kiddush Hashem nor a sign of heightened intelligence.
