Follow the steps listed below, and by using the bra size chart and how to measure, you will be amazed at how much you will love wearing your bespoke bra, designed especially for you.
My sizing is “true to size”, so always order the bra size that fits you best if you were to purchase in-store. Tell me of any, even the slightest fitting issue. Armed with your usual size, fitting issues and measurements gives me the information I require to customise your fit.
For example:
According to my size chart, I measure as a 12D. So as a client, I would note that I usually buy a 10DD but it always feels a bit tight through the band, and most underwires are too wide and too high, often at both the sides and the centre front.
Having all of this information along with measurements and underwire size, gives me everything I need to customise your perfect bra.
If you can’t find your size in the chart below, just follow the measurement guide for a custom size.

How to Measure for Your Bra
Everything you will need is included in your Custom Fitting Kit.
Three measurements are required, and, most importantly, an underwire fitting.
They are under bust, full bust and over bust.
Under bust.
This measurement is directly under your bust, around your ribcage.
To take this measurement you need the tape measure to be parallel to the floor and fitting snugly. Breathe out, and this is your measurement.
______________cm
Full bust.
This measurement is the fullest part of your bust, usually nipple height.
Wear your best-fitting bra and place the tape measure around your back and over your fullest bust area. Imagine measuring from your usual bra back around to your bust point ( nipple height or fullest part of your bust). The tape measure is roughly parallel to the floor, not firm, as we want the fullest measurement. To ensure you have captured your fullest measurement, lean forward and adjust the tape measure if required.
Full bust
______________cm
Over bust.
Imagine wearing a classic strapless dress or strapless bra. The uppermost line of these garments is your overbust.
Take your tape measure and place it as if it were the upper edge of a strapless bra. This measurement needs to be snug, so take it breathing out. The tape measure goes around your back, under your arms, and then snugly just above your breasts.
______________cm
Underwire fitting.
A bra will not fit correctly and will most likely be uncomfortable if the underwire does not fit you perfectly!
It is important to fit left and right breasts. I have provided a sticky tab to adhere left and right underwire. If the same, just tag the one that fits you. This is the most important part of the process when using the bra size chart and how to measure.
A properly fitting underwire will support, lift, and shape your breasts. It will not dig in, push down on your ribs, stab you under your arms or do any of those terrible things the wrong-size underwire can do.
The underwire needs to fit perfectly at the “inframammary crease”- the boundary where breast tissue stops and the chest wall begins. So in simple terms, directly under your breast, not digging in and not pushing down onto your chest wall or what feels like the rib cage area.

It may help to raise your right arm if you are fitting your right breast. Place the chosen underwire to your inframammary crease, and lower your arm. The underwire should feel snug, no poking and no pushing down.
Remember to fit both the right and left breast, as they may be different sizes or shapes.
Mark the underwires for left and right.
Well done!

How to measure for the perfect fit!
Measuring for undies.
Four measurements are required for the perfect fit!
They are natural waist, hips, crutch length and crutch depth.
Natural Waist
To measure your natural waist, tie the provided elastic around your waist (comfortably, not tight) then wiggle or move around, and it will settle on your natural waist. Measure snugly.
_______________cm
Hips
To measure your hips, stand with your feet together, and work the tape measure until it is over the fullest part of your bottom or hip area. Measure snugly.
_______________cm
Crutch Length
Take this while wearing your elastic around your natural waist. Place the tape measure at the centre of your back, starting at the elastic, and bring it under, through your legs to the front, up to the elastic, passing over your belly button, or somewhere near. This is more of a vertical measurement, unlike all the other measurements being horizontal.
______________cm
Crutch Depth
This measurement is taken at the side of the body, sitting down on a hard surface. The measurement is from the natural waist to the hard surface. Giving the final measurement of the depth from natural waist to crutch.
