|Huh - I never thought of that. What face shape do they work for?
Well, when I lived in Turkey one of my host families included very conservative host-grandparents. Although no one pushed me to cover, when we visited those relatives I was asked if it would be possible for me to cover just for the visits (which were usually on religious holidays). So I wore what was essentially the one piece/pull on look. And I have too little cheekbone and too much chin for it to be flattering.
I don't have any pictures of me in one (and they'd be 15+ years old anyway) but you can see "me" on my flickr page to get an idea of my facial bone structure/flab structure.
You can follow the dancing girl in my sig, but since I am the one holding the camera most of the time there aren't a lot of pics of me, and most of the ones I put on flickr are me from an angle that "fakes" the cheekbone look.
