What is the ruling on using tall cups that resemble wine glasses but are used for drinking juice, and what is the ruling on brown socks that resemble the color of skin?

It is permissible to use the aforementioned cups as long as they are not used for drinking wine. As for wearing socks that resemble the color of the skin, it is permissible for a woman if she maintains their concealment. However, it is not permissible to expose them in front of non-mahram men because they attract men's attention and arouse instincts. A woman is forbidden from anything that does so. Just as she is prohibited from speaking softly and perfuming herself when passing by men, it is all the more reason that she is not allowed to wear socks that suggest they are real skin.
