Finding your D&B Size

Your D&B size is your UK dress size combined with your UK bra size. If you wear a size 14 and a D cup bra then your D&B size is 14 Monroe.

However, dress and bra sizes vary store to store and brand to brand. For your perfect fit we therefore recommend taking the time to measure yourself using the following guidance.

(Please remember that all of our swimsuits & bikinis are made with stretch fabrics and are designed to fit a range of bodies - so don't worry too much about the odd centimetre here or there).

How to Measure

Here are a couple of tips to help you get to the right size:

- Measure yourself wearing just your knickers and a light, non-padded bra. An underwired bra is absolutely fine

- Use a fabric tape measure

- Make a note of your measurements in centimetres (cm)

- Measure yourself in front of a mirror or ask someone to help you so that the tape measure stays parallel with the floor

What to Measure

To calculate your size you need four body measurements:

Full Bust: Measure around the fullest part of your bust (this is usually across the front of your nipples). 

Underbust: Measure immediately under your bust across your ribs (this is usually where your bra band sits). The tape measure should be snug to your body.

Waist: Measure the circumference of your waist at the narrowest point. 

Hips: Stand with your feet together and measure around the fullest part of your hips and across your bottom. This is usually a bit lower than you might think (it’s the widest part of your bottom half).

Find your Dress Size

Use your measurements to see which dress size range (12, 14, 16 etc) that you best fall into.

If you are between two sizes, have measurements across more than one band or are very long in the body we recommend going up to the larger size.

Find your Curve Size

Reading across from your selected dress size (calculated in the previous step) select the full bust range that your bust measurement falls into and read down to select your curve size: Hepburn, Monroe or Hendricks.

Now combine your dress size and curve size to get your D&B size. e.g. If you measure a dress size 14 and a curve size Monroe, then your D&B size is 14 Monroe.

Bigger & Smaller Sizes

We currently offer all bikinis in sizes 8-18 and all swimsuits in sizes 8-20, with two of our best-selling swimsuit styles (the Long Sleeve and the X-Back) available up to a UK 24. If we see demand for these sizes we will continue this size extension across the rest of our range.

We are aware that our size range is still relatively limited. We’re a small independent brand and have focused initially on offering a highly comprehensive and effective set of products to women who wear dress sizes 8-20.

However we are very responsive to demand. If you would like to see more sizes in different types of products please get in touch at - we'd love to hear from you. 

For example, when we first launched back in June 2017 we tested customer demand for our products in sizes 8-16. So many of you got in touch to say that you were interested in our swimwear but needed larger sizes that within six months we expanded our size range up to UK size 20. Since then we've had lots of women ask for larger sizes and so we're delighted to have recently launched two of our best-selling styles in up to UK size 24.

We mean it when we say we're really listening to you.
