Attending an engagement party

Q: My husband and I always disagree on the topic of going to someone's engagement. I believe it is wrong because an engagement has no basis in Islam, it is not a Nikaah or anything, but my husband says it doesn't matter if it is an engagement, it is an invitation so we have to go even if it is wrong. Is it okay to go? Where does it ever say that an engagement is ok to have and to go to?

Wearing a cloak that ties above the waist

Q: Is it permissible for a woman to wear a cloak that ties above the waist, STRICTLY in front of Muslim women?

Here is an explanation: A belt that ties above the waist will make the cloak a bit tighter towards the top part of the body, it will not be loose fitting on the upper part of the body. However, the lower part and the navel to knees will be covered without showing the shape of the body. This will be strictly in front of Muslim women (e.g. a function). Basically will she be exposing her satr (her satr in front of Muslim women) in this situation?
