The Dai Ammar are located in Deir Qobel near Chouiefat. They have a holy site there. Simply visit them and you'll notice that they're not dressed in Islamic attire. You can also look at online pictures as I believe Teymour Joumblat recently made a visit there and met with their current leader.Basically, everything you said. You sound like a revisionist not a Druze scholar.
In the Epistles of Wisdom, there's two letters addressed to women and are accessible online. Neither suggests Islamic dress-code. I'm definitely not a revisionist. The Druze founders were very radical against Islam. Mohammad is called a "madman" and a "bastard child" directly in letters. So why would the Druze reject the Islamic prophecy, the Qur'an, the Islamic tenets but stick to the dress-code? I don't get your point.
