The A cup size is at the lowest end of the bra size spectrum. Most women with A-cup size may feel that their breasts are too small due to media influence that perpetuates bigger breasts as being more beautiful. But small boobs are far easier to manage, do not cause you back pains, and can be styled effortlessly.  

What Do A Cup Breasts Look Like?

Having an A cup size is pretty common, with millions of women proudly rocking their small busts. However, most ladies with this cup size usually prefer bigger boobs.

According to a survey that polled women from America and Europe on their ideal cup size, almost 53% deemed the C cup as the most preferred. Approximately 26% preferred the B cup, while only around 2% said that they like the A cup.

Regardless of what is considered the “ideal size,” women come in all shapes and sizes, each unique from the next. How big your boobs also look depends on your overall weight, height, and frame. 

For example, a girl with a small waist will have more noticeable breasts, even if she has an A cup size. The same pair of breasts will not be too distinguishable on someone with a wider torso. Moreover, the type of bra you wear can also change the appearance of your breasts under a top or a dress.

The correct fitting bra will provide you with a more defined silhouette and even impart some curves to your otherwise slender frame. You can also go for a padded bra to enhance the appearance of your boobs. However, you can only achieve all this with a bra that fits you perfectly.

Therefore, you should get yourself professionally measured or find out your bra size with the following steps:

  1. Wrap a tape measure around your body, aligned right under your breasts where a bra band usually sits. Note the measurement in inches. This is your band size.
  2. Next, place the tape measure across the fullest part of your breasts and note the measurement in inches. This is your bust size.
  3. Lastly, subtract the band size from your bust size to determine your cup size. An A cup size denotes a 1-inch difference.

A Cup Size Examples

Not all breasts that fit into an A cup bra size appear the same. Depending on your band size, your boobs can look drastically different yet beautiful. Let’s take a look at some of the women who wear bras with A cup.

32A

The woman in the picture has 32A cup size and wears a black, sheer bra with a sturdy mesh that provides her breasts with a slight lift. The slim waist and the bra style make her boobs appear fuller than their original size, giving her modelesque figure some curves. 

34A

In comparison to the picture above, with a 34A size, the boobs in this picture look smaller due to the wider band size. Since the bra she is wearing was designed to provide a comfortable fit instead of a cleavage, her breasts are not very noticeable. 

36A

The woman in the pictures wears a 36A mesh bra with lightweight, flexible underwires. The underwire makes the breasts appear perky, while the sewn cups mold the contours perfectly without any gaps. Despite the bigger band size, the woman has a flatter stomach, making the boobs appear slightly more prominent. 

40A

The individual here has a 40A bra size, which is one of the rarest sizes due to the stark contrast between the band size and cup size. The breasts look small compared to the torso, yet the bra style provides them with some shape.

Top Bras for A Cups

Women with breasts that fit into an A cup do not need a bra for support, unlike the bigger sizes. What they want from a bra are some coverage, a more defined shape, and some cleavage. Therefore, check out the best bras for an A cup size that will give you the coveted curves and make your boobs look even more beautiful. 

Padded Bra

Padded bras are a game-changer for women with small breasts. They are different types of padded bras that offer varying comfort levels and coverage. Therefore, the best-padded bra for you will depend on what makes you feel comfortable and confident.

Look for a bra that has a padded covering over the entire cup. These bras are exceptionally flattering, snug, and cozy. They also make your chest area look naturally fuller. Moreover, make sure to opt for a well-fitted design, as ill-fitting padded bras can be quite uncomfortable. 

Finally, invest in a good quality bra that is able to maintain its shape and style despite regular use. Low-quality padded bras often lose their shape, with the padding getting lumpy or moving to one side after multiple washes.   

Push Up Bra

Push up bras are the ultimate solution to the lack of cleavage. They are perfect for women with small cup sizes like the A cup size. These bras are designed to scoop and lift the boobs to create an attractive décolletage. The best push up bras prioritizes comfort along with shape.

The padding of a push up bra is positioned underneath the breasts to provide them with an accentuated lift. Most push up bras can provide an illusion of a two-cup raise for small-chested women quite naturally. You can also find push up bras in the strapless variety. 

In fact, women with A cup size can easily carry off a strapless bra without the fear of it slipping down or moving around. Therefore, if you want to wear an off-the-shoulder dress or a strapless top, look for an adhesive push up bra that allows you to keep your shoulders bare and provides some cleavage. 

Regardless of how good your boobs look in a push up bra, you should not wear them all the time. The bra design constricts and alters the shape of your breasts, causing lasting pain and discomfort.

Wireless Bra

Wireless bras are incredibly comfortable, much more than their wired counterparts. So why do we have wires in the bra?

The underwire shapes the base of the cup, lifts your boobs, and separates your breasts from each other. It also provides a level of support and helps the bra lie flat against your underbust area. 

However, if you fit into an A cup bra, you do not need the extra support offered by the underwires. The support offered by a quality wireless bra should be sufficient for your small breasts.

You can look for wireless bras that come with seamed cups, which are cups made with multiple fabrics pieces stitched together. These act as a supportive feature in place of the underwire and provide an appealing shape to your bosom. However, the seams might be visible under a tight-fitting top.

Frequently Asked Questions

Is A Cup Bigger Than AA Cup?

Yes, A cup is bigger than an AA cup. When the concept of bra cup sizes was first introduced in 1937 in the USA, there were only four sizes ranging from A to D. However, when brands realized that the sizes were not sufficient to cover the wide range of breast sizes, they introduced AA as a size smaller than A.

Is A Cup Bigger Than B Cup?

No, A cup is not bigger than a B. It is, in fact, one size smaller than B, which has a 2-inch difference between the band size and the bust size. The variation between A and B cup sizes is not very huge, but you can not, for example, wear a 34B bra instead of a 34A bra. 

How Many Inches Is an A Cup?

An A cup means that there is a 1-inch difference between your bust size and band size. In other words, your boobs protrude out just 1 inch from your chest wall, making the A cup size quite small.  Each consecutive bra size denotes a 1-inch increase. 

How Much Does an A Cup Weigh?

A breast that fits into an A cup typically weighs around 263.3 grams on average. However, the weight is just an estimate as it can vary depending on the amount of breast tissue of each individual woman.  

Fun fact: Each A cup weighs roughly the same as the weight of two chipmunks. 

What Are the Sister Sizes of A Cup Size?

Sister sizes are a range of sizes that have almost the same cup volume. Consequently, you can wear an alternate bra size if the current one feels too tight or too loose. However, there are some rules to follow when it comes to choosing a sister size. 

The general rule of thumb is that if your bra feels tight, you can go up a band size, but you should also go down a cup size. Contrarily, if your bra band feels loose, you can go for a band that is a size small, but you should increase the cup size. 

According to this rule, for the A cup, you can find a sister size up in th AA cup range and a sister size down in the B cup range. Check out the table below for a range of A cup sister sizes:
