All You Need to Know About 34A Breast Size

Breasts come in all shapes and sizes. Some are large and some are small. Some are round and some are shaped like tear-drops, perky and some point south. Half the population of the world has breasts, and some men have breasts too, usually referred to as ‘man boobs’. What makes them so special for women, of course, is the fact they produce milk for our offspring.

What do 34A Breasts Look Like?

Although 34A breasts (34 A cup, 34 A boobs, 34a busts) are very common, the average bra size is larger than that. Ten years ago, the average bra size would have been a B cup, although perhaps larger and fuller B cups. Over the last decade, we have seen the average bra size increase to a C cup, and it is now believed that most women across the globe are rocking either a C cup or a D cup. With ‘sister sizes’, it is possible to fit in 34A as well as 32B, something to know when wondering about 34a vs 34b in a breast size comparison side by side.


A number of things are said to be behind this rise in breast size, although the contraceptive pill is one of the biggest culprits. The hormones are said to come with side effects that include weight gain, increased breast size, and more bloating, as well as plenty others. Other types of contraceptive, such as the implant or patch, can also come with similar side effects.

Of course, weight loss and weight gain have an immediate effect on shape and size of breasts, and across the USA and parts of Europe, women are faced with a rising obesity crisis. The more weight you put on, the more your breast size will increase. With the average dress size increasing, it just makes sense that the average bra size would increase too.

Alongside weight gain and the contraceptive pill, breast implants have also led to the rise in average bra size. More and more women are opting for cosmetic enhancements, and the surgical procedures are becoming more readily available to ‘normal’ women, rather than just the rich and famous.

34A Natural Breasts

Did you know that most women have one breast larger than the other, and it’s usually the left breast bigger than the right one too? This can make buying bras and clothes quite difficult, but there are ways to make your own life easier. T-shirt bras and bras with removable padding or gel inserts can be used to help even things out if things are noticeable between the two. That’s if you don’t want to get into the realms of surgery, of course.

34A Breast Implants

It has been said that over 70% of women are unhappy with the size of their breasts, with A-cup sizes being one of the smallest sizes of bra that you can buy. The band that goes around the back is quite wide, suggesting that the woman rocking it will usually have quite an athletic build. The cup of the breast itself is not as full as other, larger sizes.

Breast implants will, of course, require surgery, an invasive method of breast enlargement that will take up to twelve weeks of recovery. During this time, moving around will be quite difficult, so going to work will be almost impossible. Although, to be fair, not quite as impossible as moving around with the size of breasts that the infamous Annie Hawkins-Turner sports. She is said to have the largest natural breasts on the planet, and they’re a whopping 48V bra size!

How 34A Looks with Clothes On

In China, you can actually study and then get a degree in the art of bra sizes and sizing. To be fair, many women feel as if they need a degree to understand the bra world. One size will fit entirely different in one shop than it will in another, and that’s why we would always recommend trying them up in the fitting room if you don’t want to be sorely disappointed when you get home.


Another great trick is to get yourself professional measured. When you do this, you can be sure that you are buying the correct bra. The correct size bra will not only make your breasts look better, but the entire outfit will be much more flattering (and comfortable) when you have the right fitting undergarments. Being a 34 a cup or 34a breasts all have different looks depending on the outfit top and bra.

Comparison with Smaller Sizes

Smaller than 34A bra sizes (34a cup or 34 a boobs), you have 32 and 30 band sizes, and some manufacturers and designers have created smaller bras also, such as 28.

Smaller than an A cup is an AA cup.
