Bras come in different band and cup sizes. The band will be a number, like 8, 10 or 12, while the cup size will be A, B, C etc. You will wear many different size bras in your life, so while you are growing so quickly you should measure yourself every 6 months.

If your bra fits well, it will be comfy and supportive. If your bra does not fit properly it may cut into you around the back, or under the cup. The straps may dig into your shoulders, leaving marks or the straps may be too loose and fall down your arms.

The most important thing is you don’t want to have to think about your bra when it’s on. It should just feel part of you.


Here is a measuring guide for you to find the right size bra:

You will need a soft measuring tape (like the ones you would find in a sewing kit).

Step 1 - Under Bust Measurement (Band Size)


Band Measurement

Wrap the measuring tape around your body just under your bust. Hold it snug to your ribs and measure.

Enter the number into the Under Bust Measurement box and remember to let us know if it's inches or centimetres (cm)


Step 2 - Bust Measurement (Cup Size)


Band Measurement

Take your measuring tape again, wrap it around your back and across the fullest part of your bust – usually across the top of the nipple area. Enter this number into the Bust Measurement box. Make sure your measurement is inches or centimetres, the same as in Step 1.
