Sister bra sizes are alternate sizes where the cup volume stays the same even though the band size and cup letter change. The reason is that cup sizes aren't consistent by letter, they're consistent by band size. Larger the band size, the larger the cup. Therefore, the cup of 34B is the same as 32C or 36A.
In terms of sister sizes, yes size 34B and size 32C is bra size equivalents. 34B and 32C are the same exact cup sizes, the only thing that changes is the length of the band.
A 32C is one cup size smaller than a 34C.
That number represents your cup size. For less than one inch you are a AA cup, for one inch you are an A cup, for two inches you are a B cup, for three inches you are C cup, for four inches you are a D cup and for five inches you are a DD cup.
Sister sizing takes a 32C and makes it equivalent to a 34B and a 30D too! This gives you so much more scope to explore the world of lingerie styles, sizes and more.

If there's a 1-inch difference between bust and band you're an A cup; 2-inch difference is a B cup, 3 inches is a C cup, 4 inches is a D cup, and so on. For example, if your bust measurement is 37 inches and your band is 33 inches, you would be a D cup because of the 4-inch difference.
"B" cup is considerably small than average, and it is considered being small bra size. 32 is the band size which is the measurement around your chest, under the breasts where the band of the bra sits.
A 34b cup bra and 36c cup bra are considered true cup sizes and most women wear these sizes without even measuring themselves!
How Big Is 34B? A bra size that's 34B has an under-bust size between 33-34 inches and a bust size between 35-36 inches. Being a B cup means that your bust size is two inches more than your band measurement.
Cup size is measured by the bust measurement (including the breasts) minus the rib cage measurement taken just underneath the breasts. For example, a woman with smaller breasts might fit best in an A or B cup size while those with larger breasts might fill out a C or D cup.
It is less common to find your size in some lingerie stores and intimate apparel departments because of the tendency to only stock “core sizes” — which in bands means 32–38. There's just so much physical space to display all the bra sizes out there—which can run from 28–56 bands and A-N cups!
However, a 34B is also equivalent in cup volume to a 30D, 32C, and a 36A. All three aforementioned sizes are a B cup despite what their cup letter indicates. This is called sister sizes.
For an example, a 32C and a 34B are the same cup size. The only difference is the band size. The 34 is a bigger band size than a 32. Another example, a 34B and 36A are the same cup size.
Yes, both of them are different from each other. The 34C bra cup is larger than the 34B bra cup. The letters A, B, and C in a bra indicate the size of the cups, while the size of the waistline is indicated by the numbers (34,32, and 36).
Is C Cup Big or Small? Contrary to popular belief, a C cup is not a large size. It is the most common size among women who have breast augmentation or breast implants. Having a larger chest isn't ideal for women since it can affect their posture and cause shoulder and back pain.
If C cups are the midpoint or medium breast size indicator on the cup size scale, then D cups mark the transition towards larger breasts and DD cups are the exact opposite of A cups.
With standard sizing, you can expect a 32C and a 32D to be bracketed together as a Small, a 34C and a 34D to both be Medium, a 36C and 36D to equate a Large, and so on, up through the fit range.
Measure your overbust to determine your cup size. Example: If your underbust = 73 cm, your band size is 34. If your overbust = 85 cm, in the 34 band size chart, your bra size is 34B. The measuring tape should be somewhat loose and measured at the fullest part of your chest.
Proper cup fit is influenced by band size. As the band size changes, so does the cup size. For every band size you go down, you should go up one cup. If you are in a 34D with a good cup fit, but want to go down to a 32 band, you would go to a 32DD for a tighter band with the same cup fit.
