Don't know if this has already been mentioned: Roselyn, Oakland, CA
510-444-7472 has bras to size 56H. They have catalogs and mail order
available. I don't know if they have nursing bras per se, but many of my
patients prefer the athletic or "sleep" bras which are stretchy, not
binding. Some people find these styles easier than snaps and clips.
