What's the difference between a single cup (eg a D cup) and a double cup measurement (eg DD)?

What is the difference? What does it indicate?

DD is bigger than a D but smaller than an E. Basically an in between size!

Not quite sure what you are asking ? The DD is bigger, by the same amount as between an A and a B cup. A DD cup size means the breast have more volume than a D, whereas a 34 to a 36 means the ribcage is wider at the point under the breasts. Does that help or have I missed the point?

It's like a half size in shoes I think.

No its not like a half size, it is a full size larger, but D cups were a late addition, and then they named the next size a DD and as cup sizes were developed and bras changed an E was added etc. There used to be an EE sometimes but now you only see that in US bras, here we go straight to an F. Here we go AAA, AA, A, B, C, D, DD, E, F, FF, G, GG, H, HH. But in continental bras they tend to go from D to E, F, G, H etc. so you have to work out how many sizes along from A you are to compare.

So is an AAA smaller than an AA and an AA smaller than an A? But a DD is bigger than a D?

No A is smallest, then AA is larger and AAA larger again.

AA is smaller than A I think

This is funny grin

think of bras as being on a number line in the early days:

1 2 3 4

Then body shapes changed slightly and the biggest cup size wasn't enough for some ladies. They didn't imagine that they would need even bigger bras, so they just tacked "DD" on the end.

Then they needed another size, so they expanded to E.g. Same story as with D, so they use EE. And with F. They get the hang of it after that, and over time, they add G,H,etc., right up to MM.

As fashions changed, instead of ladies with smaller breasts going without bras, they wanted bras that fit, too. A had already been used, so they followed battery logic:

AA (smaller)
AAA (smaller still)

Wow thanks for clearing that up I had no idea the double/triple lettering worked like that with the A cups blush

So A's go down in size as you add A to the name and B's and the rest go up?

I had always wondered this as I am a AA and I know this is smaller than an A.

But other sizes seem to imply more bigness as you add letters
