My 55 year old SIL is a psychiatrist. She has recently taken early retirement. My 80 year old MIL (ex-MIL, to be strictly accurate) lives in her own home of 58 years, with a hired live-in companion during the week, spending weekends with either my SIL or my ex and his wife. Absurdly, this question is about bras. My MIL has put on a little weight so that her bras no longer fit comfortably. "So" she has thrown away all of them, except one. You know, like you do before you've found others you like... Anyway. My SIL has taken her on three abortive shopping expeditions, including an appointment with an experienced lingerie fitter; in addition SIL has run two errands exchanging unsuitable bras. All have been rejected. SIL is fed to the back teeth with this performance. But meanwhile MIL has only one bra: this gives her an authentic need for new underwear and therefore a juicy grievance. The current paid companion (they have trouble keeping them. For some reason) is new this week and not yet up to taking MIL to the mall. I have run out of suggestions. There is no mileage in saying to my MIL 'whose fault is it anyway', and her build means that she cannot comfortably or hygienically go without foundation garments. I feel that my SIL has been set up and trapped. What can she do to end this farce?
