Welcome to our easy at-home fitting guide to help you find your right size.
Measuring yourself is also a good idea before visiting a professional bra fitter so you know if you're getting an accurate size from them.
You can follow this guide by yourself using a mirror or ask someone to help you if you prefer.
If you would like some bra recommendations for your size you can request a Free Size Consultation.
Step One - Put on your best fitting bra
Standing in front of a mirror put on your brest fitting bra (avoid padded, sports, minimizer and moulded bras).
Step Two - Measure around your ribcage
Measure around your ribcage using a fabric tape measure. The tape measure should lie flat against your body but not pulled tightly.
Make sure the tape measure is level with the floor all the way around your ribcage. Write down your first measurement in inches.
Step Three - Measure around the fullest part of your breasts
Pass the tape measure around the fullest part of your breasts (over your nipples), again ensuring that it is level all the way around. Write down the size in inches.
Step Four - Work out the difference between the two sizes
Subtract your Ribcage Measurement from your Full Bust Measurement. For example:
Full Bust Measurement = 39
Ribcage Measurement = 31
DIFFERENCE = 8 inches
Step Five - Find your size
Your ribcage measurement is your band size. If you had an uneven number round up one inch to get your band size. For example if you measured 31 then your band size would be a 32 (use your exact underbust measurement to find your cup size you only need to round up to find your band size)
Compare your Difference Number to this table to find your cup size:
|Difference in Inches||4||5||6||7||8||9||10||11||12||13||14|
|North American Sizes||D||DD||DDD||G||H||I||J||K||L||M||N|
NB: Lots of charts show a UK DD to be the same as a North American DD and a UK E to be the same as a US DDD but we simply haven't found this to be true. Of the styles we carry a UK DD cup is the same as a North American D cup.
Using our example above (a Difference Number of 8) your sizes would be:
32H in North American brands
32G in UK bands
Your Size Alternatives
Depending on your body shape and the brand of bra you may need to try a different size.
Lots of women prefer to wear a band size larger and cup size smaller. How to work this out is easy:
If you go up in a band size you come down in a cup size
If you go down in a band size you go up in a cup size
Use the charts below to see which other sizes you can wear and read this post.

There are other factors that affect perfect fit, the style of bra for example, but knowing your size is a great place to start.
