Women Awrah

AssalamualikumI have two questions related to marraigeQuestion 1: We know that it is haram to show the full body to anyone except your husband. Even a woman cannot show her full body to a woman. The problem is that before marraige or during marraige, a woman needs to keep herself prepared at all times for her husband i.e she needs to remove excess hair from her body. Not all women suffer from extra hair, but some really do have a big problem. So, in that case, it is difficult for a woman to help herself remove the hair and thus she needs help of another woman. My questions is that, if the husband really wants u to get the hair removed, then is it haram to show the body to a woman? since you are doing it for ur husband and no other intention...? and also, wat are the parts of the body which are permissible to be exposed to only a woman.Question 2: If a husband has given the permission to a woman to tell him directly without hesitation if she does not feel like having intercourse with him, is it still haram for the woman to say "no" to her husband when he feels like having intercourse? can she tell him "no" in this case as he has granted her permission to do so? or she should still hide her feelings and be ready for her husband at all times?

Assalamu alaykum waramotulaahi wabarakaatuh, May Allah reward the shaikhs and answer their duas,Amin. My question goes thus: We usually have women gatherings here  in the US for Muslim women.we do this to encourage Muslim women to engage in women only gatherings and discourage them from mixed gatherings.We put on normal street clothings[regular clothings worn here in the USA].Are there any restrictions as to what a woman can wear in front of other Musli m women if there are no fear of fitna?
