Selling half niqaabs

Q: Is it permissible to sell half niqaabs where eyebrows and forehead are exposed just to encourage sisters in their journey of covering the face ? (because a lot of times in the beginning it's hard for sisters to take a full niqaab).

Selling women's western clothing

Q: I am a young mom and don't work because of my little one. My husband isn't earning much so I recently started a business from home to at least fullfil my own needs. I sell online women's western clothes like skirts, cropped tops, jeans, etc.

I invested some money in it (my small savings I had) but the other day a thought came to my mind if it's halaal to sell such kind of clothes. Having said that most of my customers are Christians. Can you please help me if it's okay to sell such clothes to non-Muslim women?
