Question 1

Why can two people wear the same CC and look different?

Accepted Answer

The number is the same. The body is not. Chest width, existing tissue and how the sizer sits all change the picture. That is why a comparison on you is the only one that counts.

Question 2

Why is a cup letter not a volume?

Accepted Answer

A cup letter is a bra fit label, not a measure of cubic centimetres. It moves with the band and the brand. Volume is what a CC number names. A letter cannot do that job.

Question 3

Why do bra brands size cups differently?

Accepted Answer

Each brand cuts its cups its own way. A C in one shop can read as a D in another. That is why a letter is a poor target for visualisation. A sizer has a set volume you can try again.

Question 4

What does a CC number actually measure?

Accepted Answer

CC means cubic centimetre. It is the volume of that sizer, nothing else. It does not name a cup or a look. It only tells you how much volume you are comparing.

Question 5

Why is a "full C" in one brand not a number?

Accepted Answer

"Full C" is a feeling in that brand's bra, on that band. It is not 300cc or 400cc. There is no reliable chart that turns a letter into a volume. Look at the sizer if you want a number you can actually try.

Question 6

How do chest width, existing tissue and placement change the same CC?

Accepted Answer

A wider chest spreads the same volume. More existing tissue adds to it. A small shift in the cup can change shape and fullness. Same CC. Different picture. That is why you try it on you.

Question 7

How do I use two neighbouring CCs instead of chasing a cup letter?

Accepted Answer

Pick two sizes next to each other, such as 300 and 400, or 500 and 600. Try one, then the other, under the same clothes. The difference is easier to see than a letter ever is. We do not tell you which to keep.

Question 8

Why are photos of a cup size online a poor guide?

Accepted Answer

Those photos are someone else's body, someone else's bra, someone else's light. A "C cup" on a screen is not a volume and is not you. Use a sizer on your own frame if you want a real comparison.

Question 9

What is the sizer for in this decision?

Accepted Answer

To see and feel a set volume on your body. Not to pick a cup letter. Not to tell you a size. You compare, you notice the look you prefer, you decide in your own time.

Size	Best for
200–400	Smaller visual options
500–700	Mid-range visual options
1000–1200	Larger visual options
