Hello readers! This is my first blog on bra sizing. Getting properly fitted for a bra is almost becoming a norm nowadays. which is, of course, a good thing. But where we go wrong is while sister sizing (especially while increasing the band size and decreasing the cup size). I agree that it is incorrect to put someone like a 30 FF in a 36B. But it's far better than putting her in a 34E. Before bra bloggers start protesting, I'll explain how sister sizing should really work.
A girl who has a ribcage of 30 inches and overbust measurement of 38 inches is a true 30FF. It is a large cup size, but not overtly huge. However it is likely that she won't get a bra for less than 50 dollars in size 30FF. So what can she do if her bra size is not affordable? She can sister size up.

People will claim: A 30FF = 32F = 34E. so she can try the more easily available 34E. After all, it has the same cup volume, right?
 Sadly, this approach is completely wrong. Calculate yourself. What overbust measurement does a 34E give? It is (34+6)= 40 inches! But is she a 40 bust? NO! She is a 38 overbust! The cups will be too loose, and so will be the band. It is worse than putting the poor girl in a 36B, which atleast has a cup protrusion of 38 inches, if nothing else.

Then where are we all wrong?
 Actually, if you go up ONE band size, go down by TWO cup sizes. Because band sizes come only in even numbers.
So: 30FF = 32E = 34D. Which is a 38 bust, 34 band. It does make sense now, doesn't it?
A too loose cup is worse than a smaller cup in terms of offering support. Isn't it better to wear camisoles that fit snugly than wearing bras that hang like sacks? Please think. And buy proper sister sizes.
