This article in Salon magazine by Lauren Shields is a must read for all women. She decided to give up the “fashion rat-race” and spent nine months dressing modestly – and learned quite a lot along the way.
I am now working in an environment with many young secular Israelis, mostly women. I am amazed at what is acceptable, even in a semi-professional environment. Bra straps are everywhere (I know I am old, but I was taught that you shouldn’t let your slip show. Letting your bra strap show was unthinkable). I am also a bit appalled at how many people, especially young women, have tatoos. Granted, Orthodox Judaism forbids tatooing oneself, and perhaps that adds to my feelings of discomfort when I see them. On the other hand, I remember a time when tatoos were for guys who wanted to look tough.
In any case, clothing and makeup are only noticed on the first or second encounter with someone. After that their personality and behavior are what you remember about people, and then what is covered or not covered makes no difference.
