What is the ruling on designing a logo for a woman who works in adorning women, in an Islamic country, without knowing whether she will adorn women who display their adornments or not?

Adorning women is permissible in itself. However, it becomes forbidden if it involves immodest display (tabarruj) or is accompanied by a Shariah-prohibited act, such as hair extensions (wasl al-sha'r) or plucking eyebrows (namṣ). It is permissible to design a logo for adornment services as long as the wife is unaware of the type of adornment and for whom it will be, based on the principle of permissibility. However, if the prevalent practice among those who adorn themselves is immodest display or forbidden adornment, then it becomes prohibited at that point, due to aiding in sin.
