Hi,
I just wanted to point something out to you; the method of measuring for bra size that you have posted is incorrect. In fact this incorrect method, which is the one you'll usually find when searching on the internet ; is actually one of the reasons why such a large percentage of women wear the wrong size.

The error is adding 4 or 5 inches to the band size. This is not the correct way to measure; it is an old method which manufacturers no longer use to MAKE bras.

Nowadays, to get the correct size you either add 1 inch if the number is odd, and nothing if it is even. And then of course subtract that number from the bust measurement.

The support from a bra comes from the band(not the straps) so it needs to fit snugly, so that it does not ride up in the back. So obviously someone who measures 30 inches around the ribcage would get no support at all from a 34 inch band. I know this as well as anyone could since I used to wear anywhere from 34B to 38DD bras(vainly trying to find one that fit), none of them fit well. The boobs would always slip out underneath the bra and the band would go up in the back. generally I relied on the shoulder straps for support and they would dig into the shoulders.

When I discovered the correct method of taking measurements I was surprised to find I was actually size 32J ! Just in case you are thinking that I must be crazy and used the incorrect method; I ordered a bra in this size (from barenecessities.com in case you're looking for bigger bras!)and it fit PERFECTLY and supported BEAUTIFULLY, absolutely no bulging, falling out, or digging in anywhere. No bouncing around everywhere either for that matter.

So please, you would be doing a lot of women a huge favor by updating the method you posted to the correct one. Trust me on this one, I am one of those lucky girls who actually has bras that fit!
