its out of style now and nobody wears them so why are we continuing to wear them…

Because we are SUPPOSED to stand out! In 20 – 25 years man to woman marriage will be out of style, and we will still be doing it. Kashrus is unfortunately out of style for 80 plus percent of Jews – we are still doing it. Shabbos – make it 90% etc etc etc. The hat is a symbol now, wherever it came from in the past, it makes a statement that our tafkid is to do a lot of things that stand out and are not in style.
