Too small.  It's molded, and has some foam lining.  Trust me, when you already wear a 42D, you don't need any more padding.

Although it was too small, I could have made it work if it hadn't given me a rather strange shape - squished the girls to the sides, rather than having them out front.

The straps don't adjust enough for me to get the girls up where they belong.

Up to about 15 years ago, Penney's sold a wonderful, not too expensive bra.  It was all cotton, with under breast support on the outside of the cup.  The straps were cotton, too, were infinity adjustable IN THE FRONT.  It gave wonderful support.  The only bad thing was, it only came in white.  I'd buy a whole bunch, if I could only find that bra again.
