Do you advise me to buy an expensive wedding dress or to try and save its cost, fearing extravagance, given that the fiancé is well-off?

There is no objection to purchasing an expensive wedding dress as long as it does not reach the point of extravagance. However, if the dress will be worn only once or a few times, it is better to rent or borrow it to save money. A woman should choose a dress that can be worn on the wedding night and on other occasions, in order to preserve money, for wasting money has been forbidden. It is also among righteous deeds for a woman of means to make her wedding dress an endowment for her sisters to benefit from.
