did you measure this girl for a bra? how in the world can you know this? even a bra fitter can't tell the difference between those two sizes by just looking and even by just measuring-- you have to measure and then try on bras with someone who knows how to fit bras to get a truly good fit and brand. seriously, what experience do you have fitting women's lingerie? looking at big tits and their reported sizes on the internet doesn't count.

the difference in those bra sizes is so slight that in a pinch they are interchangeable. for example, i'm a 36DD which is a size that's very hard to find in most stores, so if i need to i can wear a 38D and get away with it. it's not a perfect fit, but it's close enough. most women know about this and take advantage of it.

your statement is ludicrous.
