What Is The Smallest Bra Size


No matter what your shape or size, a bra is one of the most important items of clothing that you’ll own. Not only does a well-fitted bra provide you with much-needed support to ensure your comfort, but it can also help to enhance your natural shape.

Breasts come in all shapes and sizes, and it’s easy to underestimate the importance of wearing a properly fitted bra if your breasts are on the petite side. This leaves many people wondering what is the smallest bra size, and how to know whether you’re wearing the right size of bra.

In this article, we’ll uncover the truth about the smallest bra size, as well as discussing how to check whether you’re wearing a well-fitted bra.


Is An A Cup The Smallest You Can Buy?

Many people believe that an A cup is the smallest cup size on the market. However, an A cup is not actually the smallest cup size. AA cups are widely available, and there are even a select range of brands that offer bras in AAA cups.

It’s important to understand that it isn’t just the cup size that is important when you’re looking at bra size. In fact, the cup size doesn’t mean anything without also looking at the band size. This is because an A cup on a 36 inch band will have a far larger volume than an A cup on a 28 inch band.

So, what is the smallest bra size, and how do you know what size of bra to choose?


The Smallest Size Of Bra: Uncovered

The smallest size of bra that is widely available is a 28AA. This bra has a 28 inch band, along with a bust that is less than one inch bigger than the ribcage. You’ll find this size manufactured by many different brands, including Royce.

It is possible to find bras with smaller bands than 28 inches, as well as smaller cups than AA. However, these are few and far between and are usually only available from specialist retailers. There is the option to have a bra custom made, but this is usually costly.

How Bra Sizes Work

The most important thing is to ensure that you are shopping for the right size of bra. But before you can work out what size of bra you require, you need to understand exactly how bra sizes work.

A bra size is made up of a number and a letter. The number represents your band size. This is the measurement around your ribcage in inches. So, if your band size is a 30, this means that your ribcage measures 30 inches in circumference.

The letter in your bra size represents the cup size. This is the difference in size between the circumference of your ribcage and the circumference of the fullest part of your bust. A cup size of A represents a difference of one inch between your ribcage and bust, whilst a cup size of F represents a difference of seven inches.

So, if your bra size was 32E, this would mean that your ribcage measures 32 inches, whilst your bust measures 38 inches.

The Importance Of A Properly Fitted Bra

Unfortunately, many people are wearing the wrong size of bra. The most common fitting mistake is to wear a band that is too big and a cup that is too small. This has been caused by poor fitting practices of some high street shops, who add inches onto the band size measurement.

A poorly fitted bra can be highly uncomfortable. This can lead to rubbing and potentially even pain in your back, neck and shoulders. By getting the fit of your bra correct, you can achieve all-day comfort and support, as well as accentuating your natural silhouette.


Does Your Bra Fit Properly?

It’s important to note that your bra size may vary slightly depending on the brand and style of your chosen bra. This means that although you may be sure of your measurements, finding the right bra can sometimes take a bit of trial and error. That’s why it’s so important to know what you’re looking for when you’re checking the fit of a bra.

When you put on a bra, you should always start with a ‘swoop and scoop’. To do this, reach into the cup of your bra and guide your breast tissue from underneath your armpit, into the cup of your bra. This essentially checks that all of your breast tissue is contained within the cup of the bra and not spilling out of the sides, ensuring your comfort.

If you’ve chosen a bra with an underwire, you’ll also need to ensure that the wire isn’t digging into your breasts. Not only is this uncomfortable, but digging wires can also cause damage to your breast tissue.

Next, take a look in the mirror and observe how the band of your bra fits on your back. The band should remain level all the way around, without riding up. If the band of your bra is higher at the back than at the front, it’s likely that it is too big. You can check this by testing how many fingers you can fit underneath the band; a properly fitted bra should allow you to fit two fingers under the band when it is fastened on the loosest hook.

Finally, check the straps of your bra. These should be just tight enough that they don’t fall off your shoulders, without your shoulders taking any weight. In fact, around 80% of the support should be provided by the band of your bra. If your bra straps are too tight, you might find that you suffer from back, neck and shoulder pain.

By ensuring that you’re wearing a correctly sized bra, you can enjoy all-day comfort and support, whilst enhancing your natural shape. What more could you want?

Is 32B Small?

Whilst 32B would be considered to be on the smaller size of average, it’s important to remember that the size of your breasts is individual to you and is relative to the size of your body. If your bra size is a 32B, this means that your ribcage measures 32 inches in circumference whilst your bust circumference measures two inches larger. It’s also useful to understand that a B cup in a 32 band will hold more volume of breast tissue than a 28 band, but less than a 36 band, so the cup size is also relative to the band size.
