If you see someone transgressing and don’t point it out to them then you too gets an aveira each time the person is doing that aveira.
On 16th Avenue i watched a woman walk, with her skirt above her knee and slipping too. No she was not a size 2,4,6,8,10 nor 12. When i nicely told her that not only were her knees out but slip too, she got insulted.
Anyway, her car(jeep) was parked at a pump and yes she did get a ticket. I hope she took it as a sign from above.
When shopping stores should have a full length mirror on all 4 sides so women can walk and see what they really look like. In addition to the length, the width should be a factor too.
Unfortunately, some women should take the band they have around their heads(covered sheitel) and put it aroung their knees.
