Some of these women give the reason that they don't feel comfortable with men staring at their faces/bodies (kind of ironic given how the outfit they wear draws so many eyes). They say it is about modesty.
I wouldn't demand them to take it off so I can see their face and hair for the same reason that I wouldn't demand a woman in a bikini take her top off so I can see her tits.
If on the other hand, the two of them want to take off these articles of clothing and show these body parts and feel pressured or coerced into not doing so, at least the Muslim lady's coercion doesn't include the law (in the west; outside of France) enforcing it, as the woman who wants to be topless' coercion does.
I say that we should let people wear as much or as little as they please, unless we have actual good reason (security or sanitary) not to, and the onus should be on us to establish that reason.
