How To Find Your Size for Bras

Brassie sizing has never stopped giving us women headaches. Millions of alternatives are open, tailored for equally abundant breast shapes and measurements. How to swim among those products and pick up a terrific fit for your body? This article will give you detailed instructions on how to find your size.

Remember that, just like all things fashion, some of these suggestions are not necessarily factual; they are based on common preferences and verdicts. Feel free to navigate around our tips to achieve the optimal outcome!

What Bras Are Regarded As "Correctly-Sized"?

What do we mean by "correctly-sized" here? It refers to a snug embodiment upon the first try and with the loosest hooks. Only then can you compress them as they extend - and not to mention, a comfortable bra tends to have a much longer lifespan.

First-time trials often lend a rather constricting feel - even with a correctly-sized bra - but no worry; it will not last long! After a couple of days, the bands will gradually loosen up.

But what if the bras are so big that you must attach their backside to the narrowest hooks for a snug fit? Chances are they are not made for you; adjusting your band size or trying on different lingerie would be advisable.

Also, note that some bras are of stretchier material than others, which might affect their compatibility with your breasts.

Why Are Snug Options Better Than Loose Ones?

Of course, each lady has her preferences. But there are reasons snug bras are a superior alternative.

First, no one wants to spend their hard-earned money on a brassiere that lasts only a few months. The more durable, the better! And as we established above, fit lingerie tend to endure longer against the test of time.

Also, loose bras have an annoying tendency to shift whenever we move, forcing us to reposition them every minute. How tiring! Few people have the time or energy to worry about whether the brassie will slip off or not. Hence, a sturdy undergarment for consistent chest support is ideal.

How to Find Your Size: Things to Consider

1. The Bands

For starters, here is something to bear in mind: 90% of the bra supports come from your band. Hence, it is of utmost importance that the band fits your body properly.

Let's say these bands are comparable to a building's foundation. If the house base (the bands) are too loose, it will fail to support the rest of the house (in this case, your breasts).

Furthermore, they are also the key to a slimmer appearance. A scour on Google Search will bring you tons of real-life examples about the differences between incorrect and correct-sized bras. With the right sizing, a woman might appear to have lost at least 10 pounds!

Otherwise, the results would be an unnatural big bust that makes you seem overweight, which we are certain is not what you aim for!

How To Determine Your Band Size

One simple method is to assess the number printed upon the bra's fabric, which indicates its band size.

But what if there is no number embedded? These cases are not common, but if they do occur, we are glad to show you another way to determine your band size.

All you need to do is measure the bottom of your busts (or underbust) using a delicate measuring tape. Take special care to fit this tape tightly around your body, with no looseness remaining.

Once you know the specific measurement, we suggest you round it up - preferably to the next single-digit number, which will be your final band size! Yahoo! Pretty simple, right?

Tips for Testing

But how exactly can you determine whether a band is properly sized for your body? There are two possible methods.

Method 1. Try It On and Move Around

One plausible approach is to put on the bras before moving your arms about and bouncing around. A stable bra that does not move one inch after all these fluttering movements mean good news! For such snug bras, there is no need for constant tweaking or pulling.

Method 2. Turn to A Friend

Another great decision is to bring along a companion - such as your husband, children, or friends! Ask them to sneak their fingers between the bands and your back. Their inability to do as you say means that the band is sufficiently tight.

What About The Back Fat Issues?

Back fat is a common issue among many women who start getting their way around different bras. They hate how the tight bands "squish" their skin on the top and at the back sizes, resulting in an ugly lump of meat. Even slender and athletic ladies face the same dilemma; you are not alone!

Still, our take on the matter is that you should not overthink these problems. Men - and even women - rarely glance at your back. Breasts are the one that pulls their attention!

Speaking from personal experience, we would rather have some "back fat" than unsupported breasts, which, as a result, look bulkier and much more uncomfortable than usual.

2. The Cups

Cup size is the second crucial component of bra sizing. A letter embroidered in the cup (from AA - smallest to  J - largest) signifies the size.

Choosing the right cup sizing remains the most challenging aspect of a brassie, calling for a great deal of time for informed decisions. But that dedication is a must if you do not want to end up with a brassie that fails to deliver support and comfort.

Pick up some of our advice below to minimize your hassles!

How to Determine Your Cup Size

Intimate knowledge of your own bra measurements will significantly reduce your searching spree.

To save time, you may inform the shop owner of your bra size, and they will present a bunch of options that suit these given numbers. A skilled consultant also lends terrific advice for the best brassie to buy based on how your breasts size up!

Two techniques are advised for the determination of cup measurements. Though we have our own preferences, the guidelines below will demonstrate both alternatives, allowing you to choose one that is most suited to your demands.

Method 1. DIY Measurements

Check the band measurement (which we have already given instructions) and the largest section of your bust. Subtract the cup from the band measurement. For every inch of difference, the cup sizes increase by one.

A little bit confusing? Let's look at a specific example. Suppose your bands are 29.5 inches (which we will round up to 30), and your bust size is 34 inches. Subtract 30 from 34, and you get 4 inches, equating to a D cup according to this chart.

Method 2. Visit A Store

Drop by a department shop or lingerie boutique specializing in bra fitting if you are not confident in your self-measurement skills. Unsure where to start? Let's use Google to navigate nearby stores. Before the visit, you may phone them and ask the stores these critical inquiries:

  • What size range do they sell?
  • Are their fitters licensed?
  • Do they focus on fitting? What brands do they supply?

Any regular store should stock band options of 28 to 52 and breast sizes from AA to J. It is also a great idea to inquire them about their return policy (just in case the bras fail to satisfy).

Here are some common brands recommended by many female customers:

  • Wacoal
  • Panache
  • La Perla
  • Natori
  • Freya
  • Elomi
  • Cleo
  • Calvin Klein
  • Chantelle.

Victoria's Secret is alright if you have specific preferences for the brand, yet, we recommend you sidestep it if possible. Most Victoria products cater to slim girls only, which results in limited assortments for plus-size.

3. The Corresponding Sizes 

We will conclude this list with another fundamental aspect: the correspondence between your bands and your cups. This insightful knowledge will help explain the shift in specifications whenever you increase or decrease your cup and band sizes.

Did you know 32C and 34C actually share the same cup dimensions? The sole distinction between the two categories lies in the bandwidth (which you can see from the numbers '32' and '34').

In the table below, it is not difficult to observe that each column boasts the same cup measurements but different bandwidths. For instance, 28D and 34A are identical in cup specifications. Hence, without the band size, any cup decision is meaningless.

Regarding the corresponding sizes, there are two very essential points to consider.

First, the greater the band, the bigger the cup (and vice versa). Your bra might either be a huge 38C or a compact 32C - in which the "C" from the two classes differ. "C" from 38C is bigger than "C" in 32C, correlating with the differences in their bands.

Secondly, if the band size decreases, the cup size must go up to compensate for the gap differences.

Let's say you take a 34C, but now, you have gained significantly more weight - to the point that your 34 bands are no longer a comfy fit. Meanwhile, the cup measurements do not change an inch.

In such cases, you obviously want to increase your band sizes, meaning the cup must stoop from C to B. Another way is to assess the chart above, which shows that 36B and 34C are comparable.

Overall, this approach is strongly recommended for bustier women looking for extra reinforcement of a more diverse bra assortment. But again, forcing yourself to conform to these guides is not necessary; not every woman feels particularly pleasant in such bras!


1. Aside from Bands and Cups, What Other Factors Should I Pay Attention to?
Center Front Gore: This element should be flush with your breastbone. If it presses too tight against your skin, larger cup sizes or different designs are needed.

Underwire: It would be terrific if its position is right beneath the breast tissue - under the armpit, not on the cervix. For better understanding, let's pit this concept against an envelope and a letter: the envelope (underwire) should be bigger than the letters (your breast) to give ample room for the letters to fit in.

For women who purchase underwires that protrude from (or sit at the top of) your breasts, we believe they need bigger cup sizing or another bra layout to accommodate your body shape.

2. My Breasts Are Uneven. What Can I Do?

The problem is not as severe as you seem to believe! Breasts of varying sizes are a common phenomenon. We suggest you measure the bigger breast and choose the sizing accordingly.

Furthermore, some stretchy bras with detachable pads, such as the Nylon Bralette, are terrific for breasts of various sizes. It is also possible to extract one pad for a more even look.

Even better, several options are designed to accommodate two sizes simultaneously! Inspect your body to size up or down the bras for a looser or tighter fit.

3. My Breasts Have An East-West Shape. Which Brassies Will Be The Best for Me?

First of all, what is an East-West shape? It implies that the nipples point outward in opposite directions. Hence, traditional tops might be a challenge for these women, as they cannot achieve full cleavage with such loose garments!

Fortunately, compressed and full-coverage alternatives can help pull the breasts together, uplifting your bosom to a more even level. One instance is the Lace Contour Bra, whose angled cups channel the breasts to your body's front, avoiding overflow from both sides.


Our article has delivered guidelines on how to find your size for bras. Keep in mind the correlation between your cup and band measurements to achieve a snug fit! If properly donned, these items will give you an incredible glow-up, easily grabbing all the men's attention.
