Can you help me find a replacement for my fav discontinued bra?

My holy grail bra was the Sierra balconette from Understance. I've lost a bunch of weight and just measured and went to order my new size to see they are going out of business and this bra is totally sold out!

I'm very hard to fit. I just measured at 40E. No molded cup bras have ever fit, I get major gaping. I have extremely wide set, shallow, east-west breasts. This was the only bra I ever found that fit properly after extensive searching. Please help!
