Sorry, but this is incredibly wrong. They are uncomfortable with or without bras and it is because of the weight, and also because it puts unnecessary stress on parts of your body that are not accustomed to unnecessary stress, even to a small degree. It might not sound like much, but try to strap 9-20 pounds worth of weights to your pecks and walk around with them and see how great your neck feels after just a few days. It is not awesome. Additionally, the glands you mentioned to not make up the entire weight/mass of breasts. There is quite a bit of fat and tissue as well.

However, with that being said, bras do not add for comfort, but they are not the main source of the discomfort.

There's no way Tifa is 150 pounds. She is likely closer to 120-125, possibly even less because of her physique and training, and should probably be a B cup or less if we are going for accurate proportions. But she does not appear to be a B cup, so Shlup's points stand.
