This is a great bra for sleep or lounging, but is not a sports bra for those of us with a large bust.  I ordered the 42 D/E, and I was looking for something to wear for low-impact activities.  I agree with the other reviewers, it is easy to put on and it's comfortable.  I have to say I wouldn't wear it for weight lifting or Pilates, though.  Larger women need more support than this bra provides, even for low-impact sports.
