So, are you ready to say goodbye to gaping cups and hello to bras that feel like they were made just for you? Let’s begin!

Understanding Bra Sizes for Small Busts

First things first: you must know what your bra size is to find the right one for you. Ideally, what you must be looking for in a bra is that it fits well, doesn’t chaff up, burdens your shoulders, and provides the right level of comfort and support. 

To know that, we will break down this whole process into three parts: Measuring Band size, cup size, and the right size of bra. Here’s a breakdown to help you grasp the essentials:

Band Size

What it is: The band size is the number in your bra size (e.g., 32, 34, 36) and refers to the measurement around your ribcage, just under your bust, where you feel the bones.

How to measure:

• Use a soft tape measure: Wrap it snugly around your ribcage, just under your bust. Make sure the tape is parallel to the ground.
• Take the measurement: Exhale normally and take the measurement. Round to the nearest whole number. This is your band size.

See this example for clarity: If the measurement is an odd number, add 5 inches to get your band size. For example, if your ribcage measures 31 inches, your band size would be 36.

Tips to measure band size correctly:

• Always wear a well-fitting, non-padded bra or a bralette while measuring.
• Don’t pull the tape too tight or too loose; it should be firm but comfortable.

Write the number on a paper and now, let’s calculate the cup size for small busts. 

Cup Size

What it is: The cup size is the letter in your bra size (e.g., A, B, C) and indicates the volume of your breast. The smaller busts lie in the A, AA, AAA, and B categories. 

How to measure:

• Measure over the bust: With the tape measure, go around the fullest part of your bust. Make sure the tape is snug but not tight, and keep it parallel to the ground.
• Subtract your band size from your bust measurement: The difference between these two measurements determines your cup size.

See this example for more clarity: 

• If the difference is less than 1 inch, you’re an AA cup.
• If the difference is 1 inch, you’re an A cup.
• If the difference is 2 inches, you’re a B cup.
• If the difference is 3 inches, you’re a C cup.
• If the difference is 4 inches, you’re a D cup.

Finding Your Perfect Fit

For small busts, you might find yourself in the AA, A, or B cup range. However, it’s important to note that cup sizes are relative to band sizes. This means a 32A has the same cup volume as a 30B or a 34AA. This concept, known as “sister sizing,” can be particularly useful when shopping for small-bust bras.

It’s essential to find a bra that:

• Fits snugly around the band: The band should be firm but not uncomfortably tight. It should stay in place without riding up.
• Has cups that fit well: Look for bras with cups that conform to your breasts without gaping. Avoid cups that are too big or too small, as they can cause discomfort and affect the overall fit.

Keep in mind that every brand has its own sizing chart, and your size may vary between brands. It’s best to try on bras and make adjustments as needed to find the perfect fit.

Yes, the struggle is real, but it doesn’t have to be a constant battle. Let’s find you the bra that fits you well, and makes you confident, comfortable, and beautiful. Check out these 10 brands best suited for small busts.
