What does a good fitting bra look like?

Putting on your bra

You can only tell if your bra is the right size once it has been put on correctly.

The best way to put on your bra is to put your arms through the shoulder straps, then while holding the bra at the hooks and eyes, bend slightly forward and let your breasts sit in the cups. Do up the bra behind your back, with the hooks and eyes on the loosest fastening, so as the bra stretches over time you can tighten it.

Once the bra is done up, you need to scoop your breast tissue fully into the cups, within the underwires.

To do this on one side: first - hold the underwire under the cup with your fingers and, with your opposite hand, reach into the cup and lift your breast tissue up and into the cup so your breast is sitting within the wires. Repeat on the other side. Then take your two index fingers, place them inside the centre of your bra, where the wires meet; and do a little swoop up across the top of the cups to smooth them out.

The band
The band

The band should follow a horizontal line around your body, and be firm but not too tight when done up on the loosest hook. You should be able to get two fingers underneath the back. If it is riding up your back in a curve, first check that the straps are not too tight then go for a smaller band size. If it is uncomfortably tight, go for a larger band size.

The cups
The cups

The wires should sit flat against your rib cage, in the centre of your bra, and on the side. If there is fabric gaping or puckering, try a smaller cup size. If you are coming out of the top or sides of the cup, go for a larger cup size. If you are coming out the bottom of the bra, try a smaller band size and larger cup size.

The straps
The straps

Adjust straps to a comfortable tension. They shouldn’t leave a painful red mark. Straps are there for balance, rather than being relied on to provide all the support. Most of the support should be coming from the band, or the cradle of the bra.

Working out your size from your current bras

Rather than using measurements, often it is easier to predict your true bra size based on how your current bras are fitting.

As with any clothing and shoes there is often some variation, and this is normal. There are a few styles that fit significantly differently to the norm. We have noted these differences on their product pages, and given you our recommendations for size adjustments.


If the band size fits, but the cup size is too small:
Keep the band size the same, and go up a cup size e.g. 12DD to 12E, 16FF to 16G.

If the band size fits, but the cup size is too big:
Keep the band size the same, and go down a cup size e.g. 12DD to 12D, 16FF to 16F.

If the cup size fits, but the band is too small:
Go up a band size, and down a cup size, this keeps the cup the same volume e.g. 12DD to 14D, 16FF to 18F.

If the cup size fits, but the band size is too loose:
Go down a band size, and go up a cup size, this keeps the cup the same volume e.g. 12DD to 10E, 16FF to 14G.

If the band AND cup are too small:
Go up a band and keep the cup the same letter, this will give you more space in the cup e.g. 12DD to 14DD, 16FF to 18FF.

If the band AND cup size are too big:
Go down a band and keep the cup size the same letter, this will reduce the space in the cup e.g. 12DD to 10DD, 16FF to 14FF.

What are equivalent cup sizes?

Bra sizing isn’t as straightforward as you might think. If your bra size needs correcting, you most often need to adjust both the number AND the letter of your bra size to get the right fit. Otherwise, if you are wearing a 14DD and size down to a 12DD to get a firmer fit, the cup size will actually become smaller too.

Equivalent cup sizes are all about allowing for the right volume in the cup, and then adjusting the band size as needed.


The best place to start is here: find your ‘best-fit’ bra size in the grid below. Your equivalent sizes are those on either side. These keep your cup size the same volume but allow for bra styles that are a firmer or looser fit than the norm; or, if you have changed size and need more, or less room around your torso.

e.g. A 14DD is the same volume of breast tissue as a 12E or 16D

Bra too firm – move to the size on the left.
Bra too loose – move to the size on the right.

Working out your size using measurements

Our bodies change so often and bra styles will fit differently, so we recommend getting professionally fitted or giving yourself a new measure every time you need to update your bra wardrobe.

Body Measurement
Measuring your torso

Measure around your body just underneath your bust, keeping the tape measure firm and straight. We would prefer the measurement in inches, but we can convert from centimeters for you.

Cup Measurement
Measuring your bust

Measure across the fullest part of your bust while wearing your best fitting, non-padded bra, again keeping the tape measure straight the whole way around.

What's next?

Provide with these measurements and we’ll do all the thinking for you. When using a measurement chart, there are more cases where the rules don’t work, than when they do. We’d love for you to get in touch once you have taken your measurements, so you can benefit from our expertise and product knowledge. That way we will maximise our chances of having you feeling amazing in the correct size, first time.

Extra tips

Move around a little and make sure you feel comfortable. Stretch your arms and hold them over your head to test if the bra stays in place. Unfortunately there is no such thing as a perfect absolute bra size, don’t worry about the size on the tag – it’s the fit that counts! Most women have slightly unequally sized breasts. When choosing a bra, it’s always best to look at the fit of the larger breast, and have the strap a little tighter on the smaller size – underneath a top, you won’t notice the difference.
