At Erilan we want you to find the perfect bra and we understand that wearing the correct size is of the utmost importance.

Often we find the simplest way to find your perfect bra size is just to look at the current size you are wearing and assess how well it fits - it is not always necessary to get out the tape measure and pen. Below are some important points to remember when finding your bra size:

1. If you wear a prosthesis it is important that the bra is supporting your natural breast. Do not gauge the fitting of a bra on how your prosthesis fits, as this maybe different to you natural breast if you have lost or put on weight.
2. The band of your bra should fit snugly around the narrowest part of your back and be the same height all the way round.
3. The bra should be close to the body at the front and sit evenly in the middle
4. Your breasts should be fully enclosed in the cup with no wrinkling of the fabric.
5. Your breasts should not bulge over the top or side of the cup.
6. You can run two fingers under the band.
7. Always start on the loosest hook. This way you can tighten it up as the bra stretches, giving you longer wear.
8. If you wear a prosthesis check that it is in the right position and is completely covered by the cup.

    Troubleshooting

    Here are some of the most common problems and how to remedy them:

    Bra rides up at the back or moves around
    Your band size may be too big. Try lifting your arms up to see if the band is tight enough. If it is riding up try going down a band size e.g. 14 to a 12. To keep the cup size the same you must go up a cup size e.g. 14C = 12D.

    Band digs in around body or the band is overstretched
    The band is too tight so try a bigger band size e.g. 12 to a 14. To keep the cup size the same you must go down a cup size e.g. 12C = 14B.

    Shoulder straps are digging in
    You may need to loosen the straps. If this does not work it maybe that the underband is too big and the straps are giving you most of the support. The underband acts as 80% of the bra’s support so try going down a band size e.g. 18 to a 16.

    Straps slip off
    The straps need to be adjusted so they are a tighter fit. For more support you may need to try a bra with wider straps.

    Your breasts are bulging out the top or sides of the cup
    The cup size is too small. Try a larger cup size e.g. B to a C cup.

    The fabric is wrinkling on the cups
    The cup is too big. Make sure you lift your bust into the bra. If the fabric still wrinkles try going down a cup size e.g. D to a C cup.

    The prosthesis is moving to one side
    The most common problem is the band is too big. Try a smaller band size. If the problem persists it maybe that the prosthesis is too light and you need to try a slightly heavier style.

    Breast Forms

    When ordering a breast form (prosthesis), simply enter your current bra size into the 'bra size' box directly above the 'Add to Cart' button. We will use this information to match the correctly sized breast form, giving you peace of mind and saving you from extra hassle.

    Measuring and Fitting Guide

    1. Measure directly under your bust with your bra on. Take it to the nearest 5cm. This is measurement A.

    • 70 cm = Bra size 10
    • 75 cm = Bra size 12
    • 80 cm = Bra size 14
    • 85 cm = Bra size 16
    • 90 cm = Bra size 18
    • 95 cm = Bra size 20
    • 100cm = Bra size 22
    • 105cm = Bra size 24

    2. Measure from the sternum to the spine across the fullest part of your breast and multiply by two. Take it to the nearest 5 cm. This is measurement B.

    3. Now take measurement A from measurement B to obtain the cup size.

    • A difference of 13 cm needs an A cup
    • A difference of 15 cm needs an B cup
    • A difference of 17 cm needs an C cup
    • A difference of 19 cm needs an D cup
    • A difference of 21 cm needs an DD cup
    • A difference of 23 cm needs an E cup
    • A difference of 25 cm needs an F cup
    • A difference of 27 cm needs an G cup

    e.g. If your under bust measurement was 85cm (measurement A) you would be bra size 16. If your over the bust measurement (measurement B) was 100 cm, you would take 85cm away from 100 cm (measurement B – measurement A) to get 15cm. This means B cup. So your bra size would be 16B.

    Get the Perfect Fit: A Comprehensive Guide to Bra Band Size Conversion

    Are you tired of wearing bras that don't fit? Do you experience discomfort, irritation, or even pain when you wear your bra? If so, you're not alone. Many women struggle with finding the perfect fit when it comes to bras, and it all starts with understanding bra band size conversion. In this comprehensive guide, we'll take you through everything you need to know about converting bra band sizes, from measuring yourself correctly to finding the perfect bra for your body type. You'll learn how to decipher bra size charts, choose the right bra style, and adjust your straps for maximum comfort. With our expert tips and tricks, you'll never have to suffer through an ill-fitting bra again. So, if you're ready to get the perfect fit and feel confident and comfortable in your bras, let's dive in!

    Why is Bra Band Size Important?

    Bra band size is one of the most crucial elements of finding the perfect bra fit. It is the measurement taken just below the bust, where the band of the bra sits. The band should fit snugly around your ribcage, as it provides the majority of the support for your breasts. If the band is too loose, it won't provide adequate support, causing your breasts to sag and putting unnecessary strain on your neck and shoulders. If the band is too tight, it will be uncomfortable and may dig into your skin, worsening lymphoedema or even causing breathing difficulties.

    Understanding the Bra Band Measurement System

    The bra band measurement system is usually expressed as a number, ranging from 08 to 32 (in Australia). It's essential to note that the band size is not the same as the cup size. The cup size is determined by the difference between the bust measurement and the band measurement. For example, if your bust measurement is 100cm, and your band measurement is 85cm, your cup size would be a B.

    It's important to note that bra band size varies depending on the manufacturer and the country of origin. For example, a 34B in the UK may be different from a 34B in the US. That's why it's crucial to understand bra band size conversion to ensure you get the perfect fit.

     

    How to Measure Your Bra Band Size Accurately

    Now that you understand the importance of bra band size and have a bra band size conversion chart, it's time to measure yourself accurately. Follow these steps to get an accurate measurement of your bra band size:

    1. Stand in front of a mirror wearing a comfortable, unpadded bra.

    2. Wrap a soft measuring tape firmly around your ribcage, just below your bust. The tape should be parallel to the ground and snug but not too tight.

    3. Make sure the measuring tape is level at the front and back of your body.

    4. Take note of the measurement in centimetres.

    Tips for a Perfect Bra Band Fit

    Now that you know your bra band size, follow these tips to ensure a perfect fit:

    1. Make sure the band is snug but not too tight. You should be able to fit two fingers comfortably between the band and your skin.

    2. The band should be level all the way around your body, parallel to the ground.

    3. The band should not ride up your back. If it does, it's too loose.

    4. The straps should not be doing all the work. The majority of the support should come from the band.

    5. The band should not be too tight, causing bulges or digging into your skin.

    Common Bra Band Size Conversion Issues and How to Solve Them

    One of the most common issues women face when it comes to bra band size conversion is that they don't know which size to choose when shopping for bras online or in a different country. To solve this issue, always refer to the bra band size conversion chart we provided earlier and take accurate measurements of your bra band size before making a purchase.

    Another common issue is that women often mistake the cup size for the band size. Always remember that the band size is the measurement just above your bust, where the band of the bra sits, while the cup size is determined by the difference between the bust measurement and the band measurement.

    Bra Band Size Conversion for Specialty Bras - Sports Bras, Nursing Bras, and Mastectomy Bras

    Sports bras, nursing bras, and mastectomy bras have slightly different sizing systems than regular bras. When it comes to sports bras, it's essential to choose a bra that fits snugly and provides adequate support during physical activity. Nursing bras should be adjustable to accommodate changes in breast size during breastfeeding. Mastectomy bras are designed to accommodate prosthetics, and it's crucial to find a bra that fits snugly and comfortably so that it will hold your prosthesis securely in place.
