Hmm... I think the Playtex Just My Size has non-stretch straps on some styles. I bought two recently and one wasn't stretchy straps. I don't know how large they run, though. I do know that they used to sell an 'Almost A' cup, and they come in half sizes on the bands in some styles.
My grandmother used to work for Playtex, made bras actually, in her younger days - we always wore Playtex stuff because she got it for crazy cheap...
