B Cup Size Breasts and Bra Size [Ultimate Guide]
Bigger breasts have always been appreciated and celebrated. However, there is no perfect or imperfect breast size, as every woman is different and unique. Some women are comfortable in their slender frames and embrace their smaller chests proudly. Others are happy to have curvier bodies and bigger bosoms.
This guide will discuss the smaller than average size B cup size bra, how it can look on different bodies, and famous celebrities with the B cup size. I also explain the right way to measure your bust , as well as the perfect bras for the small cup size.
What Do B Cup Breasts Look Like?
B cup size is just a few sizes bigger than the smallest cup size, and one size larger than the A cup . It imparts slightly distinguishable curves to your silhouette and can look very appealing when styled correctly.
Since it is quite common, you can easily find your B cup size in different types of bras, something which is a challenge for women with bigger busts.
A survey asked American and European women about their most preferred bra size. According to the results, size B is the second-best with close to 26% of respondents deeming it as the ideal size. The most coveted size is the size C, while D came third with 14.4%.
The reason for its popularity is that breasts that fit into B cups are quite manageable. You can easily sport halter blouses, strapless dresses, and bandeau tops without worrying about hiding your bra straps since you can go braless!
However, wearing the right bra is not just important for large-chested women, everyone should wear a bra that fits. To find the bra that is the perfect size, you need to measure your band size and your bust size to determine the number and the alphabet that makes up the bra size:
- Take a tape measure that is soft and pliable.
- Wrap it around your torso exactly where your bra band usually sits. Make sure that it is not too tight or too loose. Note the readings in inches.
- To find your cup size, you should know your bust size. Wrap the tape measure across the fullest part of your breasts and across your back. Note the bust size readings in inches.
- Subtract the band size from the bust size to find out your cup size. For a B cup size, the difference between the two is around 2 inches .
It is important to note that not all B cup sizes look the same. Breasts that fit into a B cup will appear more prominent on a girl with a toned stomach and thin frame.
Contrarily, a woman with a wider ribcage will appear more linear, with boobs that are not too distinguishable.

B Cup Size Examples
To help you understand how the same cup size can look vastly different, I have compiled images of women all with the B cup size. However, all of them have varying band size, making their bust size appear different.
30B
When a woman has an extremely slim frame and a B cup size, it makes her bust appear proportional to her small, lean body.
The band size 30 is also amongst the smallest band sizes available in the market. The type of bra can also impact the apparent fullness of the breasts.
32B
There is not much noticeable difference between busts of girls with a 30 and a 32 band size, since the difference is mere inches.
However, the breast volume increases with each subsequent increase in band size. The bra type and overall posture also influence the boobs’ appearance.
34B
Women with 34B bra size experience a bit more voluptuousness in the figure and a slight hint of cleavage.
The bra size 34B is quite common amongst top models, as you will notice in the section below discussing celebrities with the B cup. Moreover, most of the bra models are also this size.
36B
Women with the 36B size have a slightly wider rib cage, but their B cup boobs can still look great if they wear a perfectly-fitted bra.
Thus, even if you have small breasts, the right bra can make all the difference and make your boobs appear more curvaceous.
38B
Compared to all the other cup sizes above, the breasts look the smallest in this size.
The woman with a 38 band size has a wide torso and a relatively bigger body, making her B cup size seem comparatively smaller.
