Fitting guide

How to find your perfect fit

Bra fitting is an art, not just a measurement. With 25 years of experience and over one million women fitted, we know that finding your perfect bra takes more than a tape measure. This guide will walk you through the essentials of understanding your fit at home, but for the most accurate, personalised advice, nothing beats a fitting with our experts.
A note from our founder

“A tape measure is a starting point, not the answer. In my experience, measuring alone only tells you so much. Above a D cup and a size 14 band, styles, brands and fabrics all shift the fit. That is why we do this in person — and why the guide below is only the first step.”

Measure your band

Your band sits around your body, directly under your bust. It provides about 80-90% of your bra's support, so getting the fit right is important. Wrap the tape measure firmly around your rib cage, keeping it snug but not tight, and make sure it stays level all the way around.

A few tips

  • Wear an unpadded bra if possible, or measure without a bra for the most natural result.
  • Keep the tape level across your back — using a mirror can help.
  • Breathe out gently and relax rather than holding your breath.

Find your cup size

Your over-bust measurement helps estimate your cup size. Wrap the tape around the fullest part of your bust, usually around the nipple line, allowing it to sit lightly against your body without digging in or slipping. The difference between your over-bust and under-bust measurements can help indicate your cup size, although measurements alone won't tell you everything about how a bra will fit.

A few tips

  • Lean forward slightly to help the tape follow the natural shape of your bust.
  • Keep the tape straight across your back.
  • Take each measurement twice to check your results.

Fit Check

Does it actually fit?

Your measurements are a starting point, but how a bra sits on your body tells you much more. There are three key areas to check: the band, the cups and the underwire. Here's what to look for.

Good fit
Poor fit

Bra Band

The band should feel firm and supportive without digging in or restricting your breathing. It should sit level around your body. If it rides up at the back, the band may be too loose.

Good fit
Poor fit

Bra Cups

Your breasts should sit comfortably within the cups, without spilling over the top or sides. The underwire should follow the natural crease beneath your breasts and sit flat against your chest, without resting on breast tissue. If the wires dig in or your breasts bulge out of the cups, you may need a different cup size or shape.

Good fit
Poor fit

Bra Underwire

The wires should sit comfortably against your chest, following the base of your breasts without digging in or sitting on breast tissue. When you lift your arms, the bra should stay in place rather than shifting or riding up. If the wires lift away from your body, the band, cup size or overall fit may need adjusting.

Troubleshooting

Common signs your bra doesn't fit

These are the six most common issues we see in-store — and what usually fixes them.

Band rides up at the back

If a new bra's band rides up, it may be too big to provide the support you need. However, an older bra may ride up because the band has stretched with wear.

Likely a smaller band size, also adjusting the cup size if needed

Cups are gaping at the top

Gaping can mean the cup is too large, but it can also come down to the style or construction. For example, moulded cups may not suit every breast shape, while a non-moulded style may fit more comfortably.

A smaller cup size, or a different style or cup construction

Breast tissue spilling over

If breast tissue spills over the top or sides of the cups, the cups may be too small or the shape may not provide enough coverage.

A larger cup size or a style that better accommodates your breast shape

Underwire digs in at the underarm

Wires that dig in can indicate that the cups are too narrow or the wire shape doesn't suit your body. A band that's too loose can also affect how the wires sit, pulling them out of their intended position.

A different cup shape or wire width, and check that the band fits firmly and securely

Straps constantly slipping

Straps that keep falling down may be too loose, but the fit of the band and the overall bra style can also play a part.

Adjusting the straps first, then checking the band and overall fit if the problem continues

Red marks on your shoulders

Some light marks can happen when wearing a bra, but deep or uncomfortable marks may mean the straps are carrying too much weight. The band should provide most of the support, so if it isn't fitted firmly enough, the straps may end up doing too much of the work.

Checking the band fit first, then adjusting the straps. A smaller band may help if the current one is too loose

Bra Shapes

Choose the right shape for you

Finding the right bra is about size and shape working together. Different styles offer different levels of coverage, shaping and support, so the best option depends on your breast shape, your preferences and what you want from your bra.

Balconette

With a lower-cut neckline than a full cup, balconette bras often have a gently lifted, rounded shape. They're a popular choice for creating a flattering neckline, including under lower-cut tops.

Shop Balconette

Full Cup

Your everyday bra. Full cup bras offer more coverage, with the cups designed to enclose the breasts. Depending on the style and fit, they can be a great option for everyday comfort, support and a secure feel.

Shop Full Cup

Plunge

Plunge bras have a lower centre front, making them a useful choice for lower necklines. Depending on the design and fit, they can also provide lift and shaping across a range of breast shapes.

Questions we hear often

Guidance on fitting, product options and specialist support for post-surgery needs.

How often should I be re-fitted?

Every six to twelve months, or sooner after any change in weight, pregnancy, breastfeeding or surgery. Bodies change and so do bras — elastic softens with wear.
Do I need to bring anything to an in-store fitting?

Just yourself. Wear a top you can slip on and off easily, and bring any bras you have questions about. Our fitters take care of the rest.
Are virtual fittings really as good as in-store?

Very close. On a video call a certified fitter guides your measurements, checks the fit of what you own and recommends styles. Anything you order can be exchanged if the fit is not right.
I fall between two sizes — what should I do?

Start with the firmer band and the larger cup, then adjust. Sister sizes (one band down, one cup up, or the reverse) share the same cup volume, so both are worth trying.
What if my bra size differs between brands?

That is normal. Every brand cuts to its own block, and European and American labels use different scales. Use the conversion table above as a guide and go by fit, not the label.
