Most women in my surroundings dress quite immodestly, unfortunately. But, sometimes, a woman does dress modestly. Is it a good idea to tell her something like "I like your long dress" or "It suits you to wear long sleeves"? The two conflicting considerations are:
It is immodest to speak with other women on personal issues, especially those related to their looks.
Women care about what men think of their dressing style. So, such a compliment may give her an incentive to dress more modestly in the future.
What do you suggest?
EDIT: after reading the comments and Ana's answer, it seems that the question can have different answers in different situations. Here is the specific situation that I referred to:
- The women in question are in the workplace. Most of them are not religious and probably don't know much and don't care much about halachic modesty. But, they probably do care about what men think of them.
- I am married and not interested in any of the women. My main interest is to somehow encourage non-religious women to dress more modestly.
- The question is also relevant to religious women, that are encouraged to dress less modestly, e.g, because the get compliments from non-religious men around them. Perhaps a man complimenting their modest look might have a corrective effect.
