A 32C is one cup size smaller than a 34C. That also means a 34 is two cup sizes bigger than a 30C, and so on.
Most of the women who have a moderate structure come under 34 and 36 band size and B or C cup sizes. When it comes to 34c bra size, it gets fit to the woman with a medium bust size, neither small nor big. It is one of the outstandingly elegant bra sizes.
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.
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 also means a 34 is two cup sizes bigger than a 30C, and so on.
The general rule is if you go up a band size, you should lower the cup size i.e., a 34C is bra size equivalent to 36B.
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. Sister Sizes usually run in opposite directions with one-size shifts. Confused?
Medium: 32C, 34B, 36A, 36B, 36C. Large: 32D, 34D, 36D, 38A, 38B, 38C.
Yes, Sister sizes are sizes that have the same cup capacity but a different band size. For example, someone who wears a 32C could also wear a 30D and a 34B depending on if they want a tighter or looser fitting bra.
A 34C and a 32D are actually the same size cup size. Do men know this? Do all women know this? A 34C and a 32D are known as "sister sizes" which means that the cup will fit the same amount of breast tissue and the same applies for their other "sister sizes" of a 36B, 38A, 32D, 30DD, 28E.
41% of women said that a C cup would be their ideal size, followed by 25% who said that they would prefer to have a D cup, and 22% who favoured a B cup.
Example: if your ribcage measurement is 31, and your bust measurement is 37, your bra size is a 34C: 31+3=34, so 34 is your band size. Since 37-34= 3, you've got a C cup.
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.
A 32D has a bigger cup than a 32C. The width is supposed to be the same. Thus, depending on personal comfort, brand, or material, you may use 32C or 32D.
All you need to do is a little bra math: Subtract your band size from your bust measurement to find your cup size. “The difference in inches corresponds to your cup size,” says Iserlis. For example, if your bust measures 37 inches, and your band size is 34, the difference will be 3.
An obvious sign that the cups are too small is if the underwire presses in at the sides of the breasts or if you have red marks on your breasts when you take your bra off in the evening. The underwire should enclose and cradle the breasts; it shouldn't pinch anywhere. If it does, you need to go up a cup size.
In order to determine if your cup size is too big or small, look to see if you have an extra bump of breast tissue at the top or at the sides of the cups or if you have a wrinkle in the cups or extra space in the cup.
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.
Remember: if you go up a band size, you need to go down a cup size, and vice versa. (Ex: A 34C cup is the same as a 36B. A 40E(DD) cup is the same as a 42D.)
