What is the ruling on fashion shows in women's forums, and is advice and denouncement obligatory upon those who do so, and what are the limits of permissible display?

It is not permissible to display pictures of women in fashion shows on forums, whether these clothes are intended for use outside the home among non-mahrams, because that constitutes assisting in tabarruj (immodest display); or if they are intended for use inside the home in front of mahrams (unmarriageable kin) or the husband, because it is not permissible to publish pictures of a woman wearing them on forums. Therefore, the statement of whoever says that women-only forums are not entered by men is unacceptable. It is well-known that no sane person can claim that these women-only forums are secure, as men may view them under female usernames, or participating women may share them with men. In conclusion, it is not permissible to publish such nude pictures, or pictures of fashion, and the allure, tabarruj, and unveiling they contain, even if they are in women-only forums. A woman can seek her needs directly in stores. It is also possible to publish a picture of the clothing itself, without it being accompanied by a picture of a woman. Enjoining good and forbidding evil is an obligation upon everyone who knows of it, according to their ability.
