Permissible social gatherings must be kept free of anything that is contrary to Islamic teachings

We are a group of women who organize gatherings among ourselves in which to learn about Islam and discuss the Book of Allah and the Sunnah of His Messenger. Recently some sisters came up with the idea of organizing social gatherings, then they decided to go ahead with that and began to make preparations for it. I was one of those who objected to this idea, because I thought that these events might involve some negative aspects that I think might go beyond the guidelines set out by Islam. I would like you to tell me whether I was right or not in what I think. The following may be noted about these parties: they are for women only, with no mixing, and in this regard they comply with Islamic rulings, but: 1. There is no reason to organize such parties, as there is no occasion that calls for that; the only reason is that the sisters want to hold these parties to socialize and relax, as they say. I feel that organizing such gatherings when there is no reason for it reflects a kind of weakness of faith, and complete heedlessness of the necessity to show solidarity, even if it is only emotional, when we are supposed to feel compassion for our brothers in some neighbouring countries because of what they are going through of trauma and grief. 2. In these parties, women appear with all their adornment, because they will not be wearing hijab, and I fear that there will be a lot of showing off and competing in clothes and adornment. 3. A great deal of money will be spent on these parties, for renting a hall, preparing the finest foods, and inviting women to perform Islamic nashids in which there may be vocal effects that sound like music. I think that this is a kind of extravagance and squandering of wealth, and it goes beyond the limits set by Islamic teachings. 4. They charge rather a lot of money for anyone who wants to attend, and this could lead to some kind of inequity, with some sisters looking down on others, and it could exclude those of us who cannot afford the price of the ticket, or perhaps they need that money for other things, instead of squandering it on this foolishness, at the time when we already gather frequently for free gatherings to remember Allah, from which no one will be excluded.
