Just adding to what has already been shared here. My Muslim friends all dress and wear their hijab quite different. One is more conservative and covers legs with a long skirt/dress, leggings and shirt with long sleeves. She also wears neutral colors. Another wears a more loosely fitted hijab and dresses quite colorful, she always covers her legs and shoulders (mostly the rest of her arms too), but she wears jeans and skinny jeans too.
I also don’t think you’re being obnoxious or anything. I think it is very kind of you to want to include different religions as appropriately and correctly as possible, I think that’s quite admirable!
