• Find your size

  Wearing the wrong bra size is very common, in practice it’s almost never because your body is “hard to fit”, but because the sizing system is complex. The most common mistake is measuring too loosely under the bust, which gives too large a band number and too small a cup letter relative to your actual volume. The best way to know for sure is to re-measure yourself following the steps below, ideally while wearing a bra. Step 1: Measure your band Measure your ribcage just under the bust whilFew readers

• How do I measure my bra size at home?

  Measure directly under your bust with the tape pulled snug, that gives you your band size. Then measure across the fullest part of your bust to work out your cup size. Compare your measurements with our size chart in the guide Find Your Size.Few readers

• The size didn’t feel right, what should I do?

  The most common reason is that the size was chosen based on another brand’s size guide instead of ours. Size guides vary quite a bit between brands, so a size that fits perfectly with another brand may need adjusting with us. Our tip: compare your own measurements against our size chart, which you’ll find in our guide Find Your Size. There you can easily see if you should choose a different size or band width.Few readers

• Which bra is best for a heavy bust?

  Prioritise wide, preferably padded straps, a stable band that carries most of the weight, and fabric that doesn’t stretch out of shape during the day.Few readers

• My bra doesn’t fit, too small or too big

  Many people order the same size they wear in another brand. Size guides do vary between brands though, so our size may not always match what you’re used to. We therefore recommend always re-measuring before you order, so you get the best possible fit. The body changes throughout life, and even a difference of a few centimetres can affect which size fits best. Has it been a while since you last took your measurements? Then it might be worth doing it again. You’ll find our measuring guide here: [Few readers

• Is a large bust the same as a heavy bust?

  No. A large bust is about cup volume relative to the band measurement, a heavy bust is about the weight and density of the tissue. You can have one, both, or neither.Few readers

• The underwire digs in or pinches, what could be the cause?

  This is usually down to the wrong size. If the cup is too small, the wire presses against the breast tissue, if the band is wrong, the wire doesn’t sit correctly against the ribcage. Re-measure yourself using our guide Find Your Size to find the right combination.Few readers

• The centre gore doesn’t sit flat against my breastbone, what does that mean?

  If the section between the cups stands away from the body instead of lying flat against your breastbone, the cups are probably too small, or the style doesn’t quite suit your breast shape. Try a larger cup size and keep the same band size if it feels stable, and make sure all the breast tissue is actually inside the cup before you judge the fit. In softer styles, such as bralettes or some deep-cut styles, the centre gore rarely lies completely flat, and that’s normal.Few readers

• Should I round my measurements myself?

  No, write down your measurements in whole centimetres exactly as you read them off the tape measure. The size chart is already built with ranges that do the rounding for you, so if you round up yourself “just to be safe” or take off a centimetre to land on a round number, you risk ending up in the wrong size. If your measurement falls exactly between two whole centimetres, round to the nearest whole number and don’t add anything extra.Few readers

• What are sister sizes and how do I use them?

  Sister sizes have the same cup volume but a different band size, for example 75C and 80B. If the cup feels right but the band feels wrong, it can be worth trying a size up or down in the band while adjusting the cup one step in the other direction. Read more in the Sister Size Guide.Few readers

• Why does my bra suddenly feel tighter even though I haven’t gained weight?

  The body changes throughout life, for example during menopause, even without a change in weight. If it’s been a while since you last measured yourself, it might be time to do it again, read more in our Menopause Guide.Few readers

• What type of bra should I wear when I measure myself?

  A thin, unpadded bra that fits well gives the most reliable measurement, and that’s also how our size chart was developed. A padded, push-up, or shaping bra changes the shape of your bust and adds or removes volume that isn’t your own, which easily leads to the wrong cup size. If you only have padded or shaping styles at home, it’s better to measure without a bra at all.Few readers

• How do I know if I have a large bust, a heavy bust, or both?

  Stand in front of the mirror without a bra and lift your arms. If your bust follows the movement naturally, it’s mostly about volume, if it feels heavy and pulling, it’s more about weight. If it’s your shoulders and neck that feel tired after a long day, that also points to a heavy bust.Few readers

• Why does my “usual” size feel different in different bra styles or brands?

  The bra sizing system is unintuitive and quite complex. A bra size consists of a band size (number) and a cup size (letter). The cup letter isn’t a fixed volume, it’s a ratio, the difference in centimetres between the measurement under the bust and the measurement over the bust. When the band size changes, the cup letter has to compensate to keep the bust volume the same (so a D cup on a 75 band is smaller in actual volume than a D cup on an 85 band). On top of that, different brands cut their pFew readers

• Why doesn’t my bra band match the measurement in the size chart?

  If you measure the total length of the bra band yourself, you won’t get the same figure as stated in our size chart. For example, the band might measure 85 cm without the size therefore being 85B, the size is instead based on your underbust measurement, not the band’s actual length.

• Why does the black bra fit tighter than the white one?

  This is because black fabric is more heavily dyed, which gives it a stiffer feel. That can make the bra feel like it fits a little more snugly, even though it’s the exact same size.Few readers

• Why does the edge fold, the bra chafe, or my bust feel squeezed?

  The most common reason is that the bra is too small. This is especially noticeable on soft bras/wire-free bras, and sometimes on sports bras too. Try a size up, or re-measure yourself using our size guide to find a bra that feels right.Few readers

• Does it matter which day I measure myself?

  Yes. Your bust can feel fuller in the days before your period, after a big meal, or during hormonal changes, for example during menopause. If you measure on a day when your body is extra swollen, the measurement can be misleading for the rest of the month. So measure on a completely ordinary day, ideally morning or late morning, and re-measure at another time if the number feels unexpected.Few readers

• Which bra is best for a large bust?

  Look for a full cup with enough depth, an underwire shaped to the width of the cup, and side panels that shape and hold the bust in place.Few readers

• My breasts are different sizes, how do I choose a bra size?

  It’s very common to have some difference between your breasts. Choose your size based on the larger breast and fill out the other cup with a loose insert if you want to even out the shape.Few readers

• Why does my size come out wrong if I measure over my clothes?

  A regular t-shirt adds one to two centimetres around the body, and a thicker jumper even more. The band size in our size chart moves in steps of 5 centimetres, so that’s often enough to put you a whole size out. The cup is affected at the same time, since it’s calculated from the difference between the two measurements. So always measure directly against the skin, or in a thin, unpadded bra that fits well.Few readers

• How often should I re-measure my bra size?

  About every six months, or as soon as a bra that used to fit well suddenly feels wrong. The body changes more than you’d think over time, see Find Your Size.Few readers

• The band rides up at the back, what does that mean?

  This is a sign that the band is too big or has stretched out. The band should sit horizontally and carry most of the support, so try a smaller band size. Our guide Find Your Size will help you re-measure.Few readers

• My straps slip off my shoulders, how do I fix that?

  Try shortening the straps a little, you should only be able to fit one finger underneath them. If you have narrow or sloping shoulders, a different style with straps that sit closer to the neck may work better, see Find the Right Bra Style.Few readers
