Ordered down a cup size since Playtex bras tend to run slightly large for me and was glad I did, this bra fits perfectly.  I also have to say that so far, this is the most comfortable bra I've ever worn as well: the lining is soft and comfortable, even around the underwire, and the band doesn't cut into my skin when it's adjusted properly.  Unlike most other bras I have worn over the decades, this one doesn't shift around and ride up when I raise my arms over my head and the truly amazing thing?  It supports and uplifts my tired old girls!  Definitely a win all the way around.  :)

I'll update after a few months to comment on how well these bras last.
