Sizing Guide

Finding lingerie to fit can be an overwhelming task, particularly for larger busts.

Don't worry...
Beautifully Buxom
is here to help!

To start with, the vast majority of ladies are wearing the wrong size and or style for their shape.
After years of fitting bras I have found the ‘Boob or bust’ calculator the most accurate starting point other than fitting by eye in person.
So in order to find your ‘Beautifully Buxom’ size, your first step is to pop in your measurements to the calculator and it will give you your starting size

So many women are wearing the wrong size bra, and the high street gives very few options to get measured properly to fit modern bras. This calculator uses our algorithm to offer a starting size to then try bras. Using this, and our fit guides, you can try on bras knowing what should be happening to get your best fit.
Please enter your measurements below to calculate your Boob or Bust recommended Starting Size.

With clothes and bra off, measure underneath your bust and measure it so tight that you think that the tape might snap. This is your Tight measurement.
With clothes and bra off, measure underneath your bust tightly but still be able to get two fingers under the back. This is your Snug measurement. If you look at two fingers together, that's no more than an inch.
Whilst standing up, measure around the fullest part of your bust (ensuring you don't squash nipples if included, though gently flattening them if very pronounced may be needed), whilst ensuring the tape is level all the way round. This is your Standing measurement.
Lean over so that your boobs are dangling at 90 degrees. Measure around the fullest part again. This is your Leaning measurement.
We adjust our sizing method if you are pregnant to ensure you have space as your body grows.
If your nursling is under 8 weeks, Please contact the Boob or Bust admin via our Facebook page
We adjust our sizing method if you are under 18 to account for a growing body

I have created Beautifully Buxom’s unique sizes to accommodate a large range of bra sizes and bodies of various shapes and size, providing comfy and supportive pieces that can allow changes in size which many ladies deal with, hormonal changes, medical conditions, sensory issues, weight changes and early pregnancy while still fitting you, keeping you comfy, supported, saving money and helping reduce potential landfill.

I have been able to do this by using specific elastics, fabrics and custom made hook and eye fastenings which have additional settings to increase/decrease the under band fit which is where most of the support comes from.

How to find your unique Beautifully Buxom size.

Step 1.

It is ESSENTIAL you have a recent bra fitting, you can book with us, or use the Boob or Bust calculator which you can find on our website in the ‘Sizing’ section.

Step 2.

Find your bra size on the Beautifully Buxom size guide below.

BB Size Guide

If you usually have to ‘size up’ to accommodate your bust with tops etc, you shouldn’t have to with our unique sizing, HOWEVER, If you prefer a looser fitting fit around the waist/tummy/hips, we advise trying a ‘Top size’ UP and a ‘Bra size’ DOWN.

EXAMPLE:
You have been sized at a size 32JJ (suggested BB size S-V on the chart) BUT you usually wear a size 16 and find it a comfortable fit around waist/tummy/hips, try a BB size M-B which is one ‘Top size up’ and ‘Bra size variation’ down.

Step 3.

If you are still unsure please contact us for further help to find your perfect fit.

Top Sizes

The top sizes are made up of two sizes (Under band and cup)

  • Under band Size of 28 = XS
  • Under band Size of 30 or 32 = S
  • Under band Size of 34 or 36 = M
  • Under band Size of 38 or 40 = L
  • Under band Size of 42 or 44 = XL

The next part of the sizing is the cup part

  • If your bra size is a DD , E , F or FF your ‘Beautifully Buxom’ Size is ‘Ample’ (A)
  • If your bra size is a G , GG ,H or HH your ‘Beautifully Buxom’ Size is ‘Buxom’ (B)
  • If your bra size is a J , JJ K or KK your ‘Beautifully Buxom’ Size is ‘Voluptuous’ (V)

If you are between sizes (e.g. 32-34 or between FF-G) depending on the size top you usually buy size down to the Small as they are stretchy, or if you would rather have a looser fit on the top part size up to a Medium ,then if you would rather have a more supportive fit for the inner bra, try ‘Ample’ or for a more relaxed fit try ‘Buxom’ or you can try both and return the one that doesn’t fit or order another size to find your perfect BB fit, happy to assist with fitting questions.
