Wearing a bra is optional and this choice can change day to day depending on what you find most comfortable

Measuring your bra size at home is easy, all you need is a soft measuring tape.

Bra sizes sound a lot more complex than they are. The number, eg 36, represents the strap going around your rib cage and the letter, eg C, represents the cup size / chest volume.

To measure at home grab your soft measuring tape (important as you can hurt yourself using a hard one and it will be less accurate) and follow these steps:

Step 1: Measure your band size (underbust)

1. Stand straight and breathe out normally.
2. Wrap the soft measuring tape snug around your ribcage, directly under your breasts.
3. Make sure the tape is level all the way around.
4. Note the measurement in inches.

If the number is even, that’s your band size.

If it’s odd, round up to the nearest even number. Eg, 33 inches → band size = 34

Step 2: Measure your bust size

1. Wrap the tape around the fullest part of your breasts (usually across the nipples).
2. Keep the tape comfortably loose, not tight.
3. Make sure it’s straight across your back.
4. Write down the measurement.

Step 3: Calculate your cup size

1. Subtract your band measurement from your bust measurement.
2. The difference determines your cup size.

Cup size chart (in inches)

• 1″ = A
• 2″ = B
• 3″ = C
• 4″ = D
• 5″ = DD / E
• 6″ = DDD / F
• 7″ = G

Example:
Bust = 36″
Band = 32″
Difference = 4″ → D cup

So your bra size would be 34D.

Step 4: Try them on and experiment with "sister sizes"

Once you've identified a size, its best to try it on. Bra sizes are not an exact science instead its based on comfort, so you may decide to go up or down a size or experiment with sister sizes to find which are most comfortable for you.

Sister sizes: Sister sizes are different bra sizes with the same cup volume, meaning you go up a band size and down a cup size (or vice versa) to get a similar fit, for example, 32D = 34C = 36B, and 30DD = 32D = 34C.

So experiment! try them on and if you decide they're not for you thats okay too, we hope this helps find what's most comfortable for you!
