3 EASY STEPS TO FINDING YOUR BRA SIZE
Not sure about your size? All good, we don’t blame you! Sizing can be all over the place which is why we did our best to make finding your perfect bikini as easy as possible.
Before we start you will need a few things:
- A soft measuring tape (If you are like most households and do not have a soft measuring tape, you can use a string and hold it up to a ruler or tape measure)
- A mirror
- Your best fitting, least padded bra (no sport bras)

Step 1 - Measure your bust size
Measuring your bust to get your cup size:
- Slide your measuring tape up your back, across your shoulder blades and across the fullest part of your bust (over your nipples or see letter A).
- Keeping the measuring tape straight across your back, hold the tape as loosely as possible (without it drooping too much) and take note of that measurement.
Step 2 - Measure your band size
Stand in front of a mirror wearing your best fitting, least padded bra with your soft measuring tape to measure your band size:
- Wrap the measuring tape around your back just below your shoulder blades, just under your bust. (see letter B)
- Make sure that the measuring tape is measuring straight around your body. Pull the tape measure tight against your ribcage and take note of that measurement. (if using a string, take the part wrapped around you and hold that against a measuring tape/ruler to see how many inches it is)
- If your measurement is an odd number, add 1, if it's an even number, add 2
- Ex: 35 inches rounds up to 36
- Ex: 32 inches rounds up to 34
Step 3 - Calculate your cup size
Let’s do a little math:
- Your band measurement is what you measured + 1 (odd measurements) or 2 (even measurements)
- For every inch difference between your band size and your bust size you will increase your cup size.
- Ex: 34 inch band and a 39 inch bust (5 inch difference) will be a 34DD
- Ex: 31 inch band measurement will round up to a 32 and a 35 inch bust (3 inch difference) will get you to size 32C.
