BRA SIZE GUIDE

Welcome to our helpful bra size chart and tips to help you achieve the perfect comfy supportive fit. Let’s make sure your bra looks amazing and feels like wearing pyjamas.

5 easy steps to find your bra size 

  1. Measurements are the perfect place to start. Begin by wearing your best-fitting bra.
  2. We need two measurements for a bra size chart. Here’s how to accurately and confidently measure your bra size for the perfect fit, support and comfort.
  3. The Underbust measurement – wrap the tape measure around your rib cage just under your bust. The tape measure should be parallel to the floor and feel snug around your body. Exhale and note the measurement. This is your band size.
  4. The Fullbust measurement – Repeat the steps above this time the tape measure needs to gently wrap over the fullest bust point. Over the nipple is usually the best place. This will indicate your cup size.
  5. Now you’re ready to move on and use the bra size chart.

We are unique!

Bra sizing is calculated using our bra size guide and then lining up your measurements on the chart which will indicate a band size with a cup size. So a 12D is a band size 12 with a cup size D.

Then, just to add to the already complex calculations, there is such a thing as “sister sizes”. Sister sizes relate to the volume of the bra cup. A good example of this is, to think about a 500ml bottle of water. There is the 500ml  bottle of water that is considered to be the standard size and shape, and then there are a huge number of bottles that contain 500ml, although they are presented in many different shapes, they still contain the same volume of water- 500ml. Suddenly your bra size 12D can become a 10DD or a 14C. Confused? This is where bra size calculators need a little bit of human expertise, and sometimes a couple of trials, to find your best bra size and shape. 

Once your perfect fit is calculated, then you can really have some fun creating Bespoke Lingerie that you’ll love to wear.
