Bra Fitting Guide

Welcome to our practical fitting guide. By following our simple steps we hope you feel supported, confident and uplifted in your lingerie – and find the courage to banish those ill-fitting bras lurking in your lingerie drawer!

Always remember... 

  • 80% of support comes from the bra’s back band and only 20% comes from the bra’s shoulder straps

  • If the back band is too tight, you need to go up a back size. But remember, you must then go down a cup size for the cups to fit the same

  • If the back band is too loose, you need to go down a back size. But remember, you must then go up a cup size for the cups to fit the same

What's the best way to put on my bra?  

It’s easy! Simply place your arms through the front, lean forward, lift your boobs into the cups and fasten at the back.
This quick technique helps ensure your boobs are fully contained and supported in your bra. Fastening your bra at the front and twisting it around your back can result in unnecessary stretching and reduced support. Not such a good thing!


How should my bra sit around my back? 

An astonishing 80% of your bra’s support comes from the band of the bra which runs around your back. So, it’s important we do our best to get it right ladies! The band should fit securely, running horizontally around your back. If you put your thumb under the band and pull away you should only be able to move it about an inch from your back. 

Quick tip: stand side on in front of a mirror so you can see exactly how your bra is sitting.


What hook should I fasten my bra on? 

If your bra is new, start by fastening it on the loosest set of hooks. Over the next few months, as you wash and wear your bra, it’s normal for it to stretch a little. So, if you start on the loosest hooks you will now be able to adjust your bra ensuring the back band remains snug - keeping your boobs lifted and secure.


OK, now you have your bra on you will experience 1 of 3 scenarios... 


The band is sitting in a horizontal line around your back on the loosest set of hooks.

Yay, 1st try! This is the correct back size for you.

The band is rising up your back.

This back size is too big, you should try going down a size. 

Try fastening your bra on the tightest set of hooks. If the band is now sitting horizontally around your back, you should be fine to just drop one back size (don’t forget to start on the loosest set of hooks). If the back band is still riding up your back when on the tightest set of hooks then you may need to look at dropping a couple of back sizes. Remember – every time you go down a back size you need to go up a cup size for your bra to fit the same in the cup.

The band is sitting in a horizontal line around your back but the pressure on your chest is too much. 

Ouch! It sounds like this back size is too small; try going up a back size and this should help alleviate the pressure. You might be between back sizes, in which case we would recommend going for the bra you feel most comfortable in. For extra firmness in the bigger back size, start by wearing the bra on the middle set of hooks. Remember – every time you go up a back size you need to go down a cup size for it to fit the same in the cup.

    Should I adjust my bra's shoulder straps? 

    It’s extremely likely that you will need to adjust the shoulder straps of your bra to gain optimum support. Don’t forget that the shoulder straps provide around 20% of your bra’s support.

    If you haven’t adjusted the shoulder straps it might look like your bra doesn’t fit. To avoid this adjust the shoulder straps to around the half-way point before putting your bra on (this handy tip means that you should never need to adjust your straps too much). Next, pop your bra on (as above) and run your thumb under the shoulder straps. Your thumb should fit comfortably underneath and you should only be able to lift the straps slightly above your shoulders. If the shoulder straps are too slack simply pop your bra off, adjust the straps further and pop back it back on until you have it right.

    Quick tip: It’s much easier to do this in front of a mirror; that way you can more accurately estimate how much you need to adjust your straps.

    When you're confident the back band and strap adjustments are correct, it's time to check the cup size...  

    Once you have your bra on it’s important that you adjust your boobs in the cups to make sure they are clear of all wires. Simply pop your hand into each cup and lift up and over away from the side wires, slightly toward the centre of your body. We find it works best if you use the opposite hand to boob – i.e. adjust your left boob with your right hand and your right boob with your left hand.

    Next, you need to ensure your boobs are clear from the wires in the centre. Simply pop two fingers behind the centre wires and smooth your boobs away from the wires. This will make sure that you don’t have any breast tissue caught under the wires of your bra! The wires at the sides of the cups should sit just past your breast tissue and the wires in the centre should sit flat against your breastbone.

    Once you have adjusted your boobs into the cups you will experience 1 of 3 scenarios...


    Your boobs are spilling over the top of the cups and the wires are digging into your breast tissue

    Not such a good look! The cup size of this bra is too small for you so we would suggest trying a bigger cup size. You should be able to take an educated guess if one or more cup sizes bigger is needed. Remember; if the back band is secure you don’t need to change it.

    The wires at the centre of the cups are sitting away from your body

    One element of a good fitting bra is that the wires at the centre of the cups sit flat against your body. If they are twisting or pointing away from your body then it is likely that your boobs are pushing the bra away from you – meaning that the cups are too small. Try a cup size bigger and this should help.

    There is extra space in the cups that your boobs aren’t filling out

    This suggests that the cup size is too big for you or unfortunately the shape of the bra is not best suited to your shape. Try going down a cup size or alternatively, try some other styles. After all, we want you to feel supported and confident!

      What should I do if my back band is riding up?

      If the back band is riding up, the back size you are wearing is too big for you. Try coming down a size or two. When you start wearing a new bra you should fasten the back band on the loosest set of hooks so you get maximum wear out of your gorgeous new purchase. Remember, if you are go down a back size come up a cup size so the cups still fit you perfectly.

      Eeek! Why does it look like I have 4 boobs?

      It’s common to see the ‘4 boob effect’ if the cup size you are wearing is too small. When the cups are too small the material of the cups press against your breast tissue causing it to spill over the cups. To ensure this doesn’t happen again try going up a cup size or two until your boobs are fully contained in the cups of your bra.


      My bra straps are digging into my shoulders, what should I do? 

      If the straps are cutting into your shoulders and causing discomfort you should slacken them off slightly. However, it’s important that they don’t become too loose so try slackening them little by little until you feel comfortable. You should be able to run your thumb under the straps and lift them away from your shoulders slightly. 

      My bra straps keep slipping off my shoulders, what should I do? 

      If your straps are slipping off your shoulders they are too loose and not giving you the support you need. To ensure your straps stay in place you should adjust them to a point where it is comfortable for you to run your thumb under the straps and lift them away from your shoulders slightly. 

      Why are the wires at the centre of my bra not lying flat? 

      The most common reason for the wires not lying flat against you is that the cup size is too small. When the cup size is too small your boobs are pushing the bra away from you, causing the wires to poke forwards. Try going up a cup size or two to allow the wires to lie flat against you and separate your boobs. 

      What should I do if there is too much extra space in the cups? 

      First of all, ensure that your straps are adjusted accurately. If not, there may be some wrinkling in the cups. If you have adjusted the shoulder straps of your bra and the cups are still wrinkling it would seem that the cup size is slightly too big for you. Try dropping a cup size to eliminate the extra space. Remember, it’s completely normal to have one boob bigger than the other, so if you only have space in one cup we would recommend sticking with this size. It’s OK to have a little space, and this is much better than spilling over the top of the cups.

      Ouch! The back band is too tight, what should I do? 

      If you’re finding the back band is digging in and causing discomfort then you should go up a back size. Remember, if you’re going up a back size and the cups are fine you’ll need to come down a cup size to ensure they are still fitting you. Remember, it’s completely normal for your bra to leave an imprint as you would get with a pair of socks. 80% of your support comes from this back band so we want to make sure it’s snug without compromising on comfort.
