Clothing for Women

Q: I have been coming back to Islam since Ramadan alhamdulillah. Before Ramadan I practiced Western version of Sunni Islam by dress and behavior. Since then I'm feeling pull towards salafi methodology. 

I've begun being mentored by a kind salafi woman MashaAllah. 

She says a woman should cover with niqab and gloves any time her husband is not home, even if she's not being seen by non mahram. She said it's an act of worship and a way to show and ask Allah Ta'ala for extra protection while my husband (protector) is not home. 

Is there Islamic basis for this, is this from culture, or from her specifically? 

Q: Is it permissible for a lady to wear a colourful scarf with her black abaya and black niqaab?

Q: I wanted to ask a question regarding the dressing of women in their own homes. In my house we have our own gym area where me, my mother, and sisters exercise. While exercising they usually wear shorts that go till the knees and a low cut tank top that shows their cleavage. Their nipples are sometimes also visible sometimes. Is this allowed Islamically if there is no fear of fitnah?

Q: Is it permissible for my wife to dress in jeans, heels, and other very provocative western and eastern attire in the boundary of our home? There is no risk of anyone entering upon my wife. This is all for my pleasure, so that I am able to better guard my gaze and be satisfied at home?

Q:

1. Is it necessary for a lady to have her hair covered while sleeping, cooking and when in bed making zikr?

2. Can a lady read salaat with jeans?

Q: For women, what is the correct method of wearing a headscarf i.e. if the scarf is tied to her head and the shape of the head can be seen?

Q:  Some of my clothes are only see-through when looked at closely. The skin can only be seen underneath if there is enough light and if I look very closely but to an onlooker from afar, they would not be able to see my skin. Am I allowed to wear such clothes during Namaaz, which are opaque and not transparent but only see-through from a near distance?

Q: With regard to women's clothing, when a woman is going out, how must she be dressed? Mostly in today's time with outdoor activity, how must she be dressed (example: swimming, picnics, etc.). Please give some explanation. 

Q: My wife wears "Kaali Poth" which married Muslim women wear in Andhra Pradesh, India. Is it haraam to wear it? Will her Salaat be valid if she prays wearing it? 

Q: Can you please tell me how do we determine if a dress is transparent or not. Most of my dresses are such that if I hold them in front of my eyes, I can see whatever is on the other side. But if I put my hand below the dress or wear the dress, my body colour cannot be seen. Are these dresses considered to be transparent? What is the way of determining if a dress is transparent or not?
