Book excerpt: "Breast Health and Bra Comfort" by Geoff Kirby has been inspired by his discovery that 80% of women are wearing the wrong size bra. Of these as many as 60% are suffering discomfort, breast pain, have multiple cysts and some even develop breast cancer. Giving up wearing a bra benefits sufferers of breast cysts and breast pain. As a result of casting off their bras ladies reported improvements in breast health typically saying "Leaving off my bra has given me back my freedom. My breast pain has gone. Worry has stopped and I'm enjoying life more." However, given the pressures from the bra advertising industry most women will probably not cast off their bras despite the benefits. Given this huge urge to conform and wear a bra how can you find that perfect bra that won't pinch, strangle and possibly make you ill? Geoff Kirby has tested over twenty bra sizing online guides and has found most of them to be unreliable - some to the point of being useless. In addition, large discrepancies can exist in bra size and comfort from bras having the same size on the label. This is 'vanity sizing' where some bra manufacturers deliberately put the wrong sizes on bras to fool the wearer into thinking she is slimmer and has more 'sexy' breasts. Geoff introduces a new, simple bra sizing guide which will help you find a bra which can be comfortable, attractive and reduce your health risk.
