This is more than just buying a piece of clothing, it's a big moment in your life. We understand it might seem a bit scary, but don't worry. This guide is here to make it easier for you.

We're going to help you learn how to measure for your first bra correctly. This isn't just about finding a bra that fits well; it's about accepting the changes in your body and stepping into this new part of your life with confidence.

So, let's get started on this journey together. With this guide, you'll learn the right way to measure for a bra and step into your new role as a young woman with confidence.

What Is The Importance of a Well-Fitted Bra?

A well-fitted bra is more than just a piece of clothing; it's a crucial aspect of your daily comfort and overall health. Here's why:

  • Promotes Comfort: A bra that fits well feels good. It doesn't pinch, squeeze, or leave marks on your skin. It allows you to move freely and easily throughout the day.
  • Enhances Posture: It provides the right amount of lift and support, which can help maintain good posture. This is especially important during the adolescent years when the body is still growing and developing.
  • Prevents Health Issues: Wearing a poorly fitted bra can lead to health issues over time, such as back pain, neck pain, and even breathing problems. Ensuring a proper fit can help prevent these issues.
  • Boosts Self-Esteem: Last but not least, it can boost your self-esteem. When it fits well and feels right, it can make you feel more assured and comfortable in your own skin.

How To Measure Your Size?

Unlocking the perfect fit is a game-changer. Here's a detailed, step-by-step guide to help you measure accurately:

Step 1: Measure Your Band Size

  • Begin by taking off your top and wearing a non-padded bra.
  • With a soft measuring tape, measure around your chest, right under your breasts, where the band of it sits.
  • Ensure the tape is level all the way around and is snug but not tight.
  • Breathe normally and take the measurement in inches.
  • If you get an odd number, round it up to the nearest even number. This is your band size.

Step 2: Measure Your Bust Size

  • Next, measure around the fullest part of your chest, usually at the nipple level.
  • Make sure the measuring tape is at the same level all the way around your body.
  • It should be snug but not tight. Don't pull the tape too tight or let it sag.
  • Take this measurement in inches.

Step 3: Calculate Your Cup Size

  • Subtract your band size from your bust size.
  • The difference determines your cup size. For example, if your bust size is 33 inches and your band size is 32 inches, the difference is 1 inch, which indicates an A cup.

Remember, these measurements are a starting point. Different brands may have slightly different sizing, and variations in styles can also affect the fit. So, it's important to try on several styles to see what feels best. Also, your size may change over time, so it's a good idea to measure yourself every six months or so.

How to Check if Your Bra Fits Well?

Once you've measured and selected a brassiere, it's important to check that it fits properly. Here's how you can check:

Band Fit

  • The band should sit straight and parallel to the floor. It shouldn't ride up at the back.
  • It should be snug but also flexible. You should be able to slide two fingers under the band easily.

Cup Fit

  • Your breasts should fit comfortably within the cups. There should be no spilling over the top or sides.
  • The center of the bra, between the cups, should sit flat against your chest.

Strap Fit

  • The straps should rest easily on your shoulders without causing discomfort or sliding down.
  • They should provide some support, but most of it should come from the band.


  • Comfort is the key. You shouldn't feel any pinching or irritation.
  • Try moving around, lifting your arms, and bending over to make sure it stays in place and continues to feel comfortable.

A well-fitted bra should feel almost like a second skin. It should provide support and ease without you being constantly aware of it. If something doesn't feel right, don't hesitate to try a different size or style. The perfect fit is out there, and it's worth taking the time to find it.

Navigating the World of Sports Bras

Entering the world of sports bras is like reaching a new stage in your fitness journey. It's not just about finding a piece that matches your workout clothes. It's about making sure you have the right support to tackle your toughest workouts, especially if you have a larger bust size.

Did you know, according to research from the University of Portsmouth, that unsupported breasts can move as much as 5.5 inches during intense exercise? Such movement can risk lasting harm to Cooper's ligaments, the structures that help keep your breasts in place. This underscores the importance of finding the perfect sports bra for your needs.

Like all bras, sports bras also aren't a one-size-fits-all solution. They come in varying levels of support to cater to different activities:

  • Gentle Support: Excellent for low-impact activities like yoga and walking. This level is typically suitable for smaller cup sizes (AA–B).
  • Moderate Support: Ideal for activities like dancing, strength training, cycling, low-impact exercises like Pilates and Barre, and skiing.
  • Maximum Support: Designed for high-impact activities like running, aerobics, and HIIT. This level is typically suitable for larger cup sizes (D+).

When it comes to the fit of your sportswear, it should be snug but not too tight. A well-fitting undergarment won't leave marks on your skin, cut off your circulation, or restrict your breathing. It might sound a bit odd but try jumping around a bit in your potential pick to make sure that it's comfy and you are able to move freely without the band moving out of place. Feeling supported and secure should be your number one priority.
