Marks & Spencers sell a soft, un-wired bra which is a good shape, and would do the trick I think. It is the boning which would possibly cause a problem, and that one has just soft fabric,not lacy, but there is quite a choice if another one is preferred. Look on their web site, and an order can be placed, picked up in store or delivered, and tried on in the comfort of your own home. Just make sure you have it loose enough not to feel too tight. They would also measure you in store if required.
