How to Pick the Right Bra Size

Choosing the perfect bra size is a crucial aspect of women’s lingerie shopping. A well-fitting bra not only provides comfort and support but can also enhance your overall appearance and confidence. However, many women still struggle with finding the right bra size, leading to discomfort, pain, and dissatisfaction. In this comprehensive guide, we will delve into the various aspects of bra sizing, the importance of a proper fit, and how to measure yourself to select the ideal bra size for your body. With the right knowledge and some handy tips, you can ensure that your undergarments provide the comfort and style you deserve.

The Importance of a Proper Bra Fit

Before diving into the details of how to pick the right bra size, let’s first understand why a proper fit is essential. Wearing the wrong bra size can have several negative consequences:

  1. Discomfort: An ill-fitting bra can be incredibly uncomfortable, causing digging, pinching, and chafing. You may find yourself constantly adjusting your bra throughout the day, which is distracting and frustrating.
  2. Breast Health: A bra that doesn’t fit properly may not provide the necessary support. Over time, this can lead to sagging and discomfort, potentially even causing issues like stretched ligaments.
  3. Appearance: A well-fitted bra can significantly enhance your posture and overall appearance. It can lift and shape your breasts, making your clothing fit better and boosting your self-confidence.
  4. Prevent Back Pain: The right bra can help distribute the weight of your breasts evenly, which can prevent back and shoulder pain. This is especially important for women with larger busts.
  5. Longevity: A bra that fits well is less likely to wear out quickly. When your bra is correctly supporting your breasts, it doesn’t experience as much strain, and it can last longer.

Now that you understand the importance of selecting the right bra size, let’s move on to the steps for finding your perfect fit.

Step 1: Measure Your Band Size

The band size is the number part of your bra size (e.g., 34 in 34B). To measure your band size, follow these steps:

  1. Gather Your Supplies: You’ll need a soft measuring tape and a mirror. You may also want to wear a non-padded bra for accurate measurements.
  2. Stand in Front of the Mirror: Stand up straight, with your arms at your sides. Ensure that the measuring tape is level and not twisted.
  3. Measure Around Your Ribcage: Wrap the measuring tape around your ribcage, just under your bust. Make sure it is snug but not too tight. The tape should be parallel to the ground. This measurement will give you your band size. Round it to the nearest whole number.
  4. Record the Measurement: Take note of the measurement in inches. This will be your band size.

Step 2: Determine Your Bust Size

The bust size is the letter part of your bra size (e.g., B in 34B). To find your bust size, follow these steps:

  1. Stand in Front of the Mirror: Again, stand up straight, with your arms at your sides. Make sure the measuring tape is level and not twisted.
  2. Measure Across the Fullest Part of Your Bust: Place the measuring tape around your bust at the fullest point, usually around the nipples. Make sure the tape is snug but not too tight. Keep it parallel to the ground.
  3. Record the Measurement: Take note of the measurement in inches. This will be your bust size.

Step 3: Calculate Your Bra Size

Now that you have your band size and bust size, you can calculate your bra size. Subtract your band size from your bust size and use the difference to determine your cup size. Here’s a simple chart to help you find your cup size based on the difference:

  • 1 inch difference: A cup
  • 2 inches difference: B cup
  • 3 inches difference: C cup
  • 4 inches difference: D cup
  • 5 inches difference: DD (or E) cup
  • 6 inches difference: DDD (or F) cup

For example, if your band size is 34 inches and your bust size is 37 inches, the difference is 3 inches, so your bra size is 34C.

Step 4: Try on Different Styles and Brands

While you now have your calculated bra size, it’s important to remember that not all bras are created equal. Various brands and styles may fit differently. When shopping for bras, especially if it’s your first time using your newly calculated size, don’t hesitate to try on different styles and brands. You might find that certain bras fit better or more comfortably than others, even if they’re all in the same size.

Signs of a Well-Fitting Bra

When you try on bras, there are several signs that indicate a good fit:

  1. The Band Stays in Place: The band should sit level and parallel to the ground, staying in place without riding up your back.
  2. The Cups Don’t Gap or Wrinkle: The cups should fully encase your breasts without any gaps or wrinkles. There should be no spillage over the top or sides.
  3. The Center Gore Lies Flat: The center piece between the cups, known as the gore, should lay flat against your chest. It shouldn’t pull away or dig into your skin.
  4. The Straps Don’t Dig In: The bra straps should be adjusted to a comfortable length, and they should not dig into your shoulders.
  5. You Can Breathe Easily: You should be able to take a deep breath without feeling restricted. A well-fitting bra should provide support without constricting your ribcage.

Common Bra Fitting Issues and How to Solve Them

Even with proper measurements and attention to detail, you may still encounter some common bra fitting issues. Here are a few of the most prevalent problems and their solutions:

  1. Bra Straps Falling Down: If your bra straps are constantly slipping off your shoulders, it could be due to an overly wide band or stretched-out straps. Try tightening the straps or consider getting a bra with a smaller band size.
  2. Bra Band Riding Up: A bra band that rides up your back is usually a sign that it’s too big. You might want to try a smaller band size.
  3. Cups Spilling Over: If your breasts spill over the top or sides of the cups, it could indicate that the cup size is too small. Consider going up a cup size.
  4. Cup Gaping: Gaps between your breasts and the cups can be a sign that the cups are too big or that the style of the bra doesn’t suit your breast shape. Try a smaller cup size or a different style.
  5. Underwire Digging In: An underwire that digs into your ribcage can be caused by a band that’s too tight or cups that are too small. You may need a larger band size or larger cup size.
  6. Center Gore Not Laying Flat: If the center gore doesn’t lie flat against your chest, it might indicate that the cups are too small. Try a larger cup size.

Remember, it’s not uncommon to have bras with varying sizes in your collection due to differences in brand and style. It’s essential to prioritize comfort and support over sticking to a specific size.

When and How Often to Get Fitted

Your body can change over time due to factors like weight loss, weight gain, pregnancy, or aging. It’s crucial to re-evaluate your bra size periodically, even if you’ve previously found a perfect fit. You should consider getting fitted:

  1. After Weight Changes: If you lose or gain a significant amount of weight, your bra size is likely to change. Make sure to get fitted again to find the right size for your new body.
  2. During Pregnancy: Your body undergoes significant changes during pregnancy. You may need to get fitted for maternity bras to accommodate your growing breasts.
  3. After Pregnancy and Breastfeeding: After giving birth and breastfeeding, your breast size and shape may change. It’s a good idea to get fitted for new bras to ensure comfort and support.
  4. As You Age: The natural aging process can affect breast size and shape. Regularly check your bra size to maintain comfort and support.
  5. When You Notice Discomfort: If your bras no longer feel comfortable or you experience pain, it’s a clear sign that you should get fitted for a new size.
  6. At Least Annually: Even if you don’t experience major life changes, it’s a good practice to get fitted at least once a year to ensure you’re always wearing the right size.

Finding the Right Bra for Your Body Shape

Aside from finding the right size, it’s important to consider your body shape when choosing a bra. Different styles of bras work better for different body types and outfits. Here are some general guidelines:

  1. Full Bust: Women with a full bust may benefit from full-cup or balconette bras. These styles provide ample coverage and support.
  2. Small Bust: Women with smaller busts may prefer push-up or padded bras, which can enhance the appearance of their breasts.
  3. Pear-Shaped Body: If you have a pear-shaped body, consider bras with detailing or lace on the upper part of the cups to draw attention to your upper body.
  4. Hourglass Figure: Women with an hourglass figure can wear most styles, but plunge bras can work well to accentuate the cleavage.
  5. Athletic Build: Women with an athletic build might prefer sports bras for everyday comfort and support.
  6. Plus Size: For plus-sized women, it’s essential to find bras designed for larger bodies that provide the necessary support and comfort.
  7. Special Occasions: Consider strapless or convertible bras for outfits that require specific bra styles. These can be versatile for various clothing types.

Bra Care and Maintenance

Once you’ve found the right bra size and style, it’s important to take good care of your bras to ensure they last and continue to provide the support and comfort you need. Here are some essential bra care tips:

  1. Rotate Your Bras: Avoid wearing the same bra every day. Rotate between several bras to give each one time to recover and maintain elasticity.
  2. Hand Wash or Use a Lingerie Bag: Washing bras in a lingerie bag or by hand can help protect the delicate fabrics and underwires.
  3. Use Mild Detergent: Avoid harsh detergents and fabric softeners, as they can damage the fabric and elasticity.
  4. Fasten the Hooks: Before washing your bras, fasten the hooks to prevent snagging on other fabrics.
  5. Air Dry: Never put your bras in the dryer. Instead, lay them flat on a towel to air dry.
  6. Store Properly: Don’t fold your bras in half or stack them on top of each other. Store them flat in a drawer or hang them to maintain their shape.
  7. Replace Bras Regularly: Bras have a limited lifespan. As they stretch and lose their elasticity, it’s important to replace them when they no longer provide the necessary support.


Selecting the right bra size is an essential aspect of women’s lingerie shopping. A well-fitted bra not only provides comfort and support but also enhances your appearance and confidence. By following the steps outlined in this guide, you can accurately measure yourself and determine your perfect bra size. Remember that your body can change over time due to various factors, so it’s essential to get fitted regularly and adapt your bra collection accordingly. Additionally, consider your body shape and outfit requirements when choosing different bra styles. Finally, taking good care of your bras through proper maintenance ensures that they remain in excellent condition and continue to provide the support and comfort you need. A well-fitted bra can make a significant difference in your daily comfort and overall confidence, so invest the time and effort to find the perfect one for you.
