"I very much doubt you know any Muslim women in real life. Therefore your judgement is rendered useless"
You know a grand total of fucking zero about me, so imho should refrain from making frankly meaningless statements like "your judgement is rendered useless". 
This is not a competition for whose views are more valid according to how many Muslims they know (as you seem to think so) but since you asked, I was born and raised in a Muslim country. Nearly all of my family, most of my friends, acquaintances, and work colleagues are Muslim. One of my grandparents was a hafiz and another was a haji. I have read the Quran, not least because I had endless years of religious education on it at school.
Oh but you converted to Islam when you were 16, which means you are the bestest at knowing everything about Muslims and nobody else can have an opinion 
You can continue with this ridiculous attitude or grow up and open your eyes.
FYI neither of my very devout Muslim grandmothers covered their heads or had anything against t-shirts. Contrary to what you might have been led to believe, it is entirely possible to be a Muslim woman and NOT cover oneself up head to toe.
