This is in response to a comment on this video on "How To Measure for a Bra".
"the cup size measuring she gives doesn't make sense. She says "we had 32 and now we have 33....".where did those numbers come from? Not clear at all."
I agree with the comment, as the presenter in the video didn't seem to know what she was talking about. :-)
The 33 inches measurement comes from adding 5 to the measurement around the chest directly under the breasts. 26 inches + 5 inches = 31 inches. As bras don't come in odd numbers, as she had explained, 1 was added to round it off to 32. This is the band size. Everything's correct up to this point, but I spotted two serious errors thereafter.
She was supposed to measure around the chest at the pinnacles of the breasts - she measured somewhere above that. I believe the measurement would have been 34 inches rather than 33 inches, had she done it correctly. She foreknew that she was holding onto a cup B bra, but she got the numbers wrong, so that's why it didn't add up.
34 inches - 32 inches = 2 inches. In general, 1 inch is the equivalent of 1 cup size (cup A), so 2 inches would make it a cup B. Therefore, the size is 32B.
