What is the ruling on buying lingerie for one's wife through e-commerce websites that display naked and provocative images of models?

If what you wish to buy for your wife is lingerie with provocative and explicit images on it, it is better to leave the task of purchasing to your wife, and your avoidance of entering such a website is safer. However, entering these websites for a legitimate purpose – such as purchasing – is not forbidden for someone who is secure from temptation, provided that one lowers their gaze from what is unlawful. The presence of images is not intended for its own sake, so it does not legally prohibit entering them; because what is permissible as a subsidiary is not permissible independently.
