Here is a Dear Grace column on modesty in dress. I remember hearing a recording of a priest that said that anyone who causes a sin of lust by immodest dress is responsible for that sin. Of course, the sinner is responsible as well, I’m sure.
Besides, I find that women who dress modestly are much better looking than those who don’t. Immodest dress looks trashy to me. Truly modest dress is sharp-looking and gets attention from people whose attention is desirable.
