It is really not mechubad to come to shul on Shabbos with a shirt hanging out & not tucked in like a slob,grungy trousers & sandals with no socks, after being here 15 years I still think it is strange & shows a lack of respect to both a house of Hashem & Shabbos!!!!!! You do not see any rabbanim dressed like that not even the dati leumi rabbanim & the rabbis should be our guide how to dress properly.
