Can someone explain the odd sequence of sizes? [possibly NSFW but a real question]?

I’ve never read of anything beyond a double or triple D.

DD is the same as E and DDD is the same as F. I don’t think there’s a DDDD. Country matters, too…the US stops at N from what I could deduce. That’s not to say that some women don’t have larger bust sizes than this, but that is usually the largest bra size you will find in specialty stores. Anything beyond that is probably specifically made for the woman.

What @smudges wrote about E and F is correct. Quadruple D, is equivalent to G.

I’ve never seen beyond N cup size.

What’s sort of weird is double AA is smaller than A, but double D is bigger than D. There is AAA also.

With artificial breasts so popular in the US, it’s not uncommon for women to be double D or larger. Also, since so many are overweight we see larger cup sizes, but being overweight doesn’t always grow the breast cup size multiple cup sizes, because weight is gained around where the band goes also, but many women do gain weight disproportionately in their breasts when they gain.

Some women are naturally petite frame with huge breasts, it happens.

To give a basic understanding a woman wearing 36B, but the bra slips too much, because it is too big around her back, should be in 34C if the cup was already fitting well.

What I want to know is why there is no equivalent scaling scheme for dicks.

@ragingloli visibility. Breasts are visible (or their coverings are) at all times.

I majored in this during college years.
When bras came along, they were custom made. The number was the overbust measurement and the cup letter was the difference between under and overbust, with A being very small and D being “very large”. When bras became mass manufactured and available on shelves, they didn’t want to change the sizing system but so much, so most bras were made as 32A-C and 34–40A-DD. Spandex didn’t used to exist, so people added inches to their underbust in order to buy their off-the-shelf bra. Tons of people need bras outside of that range now that spandex and multi-part cups exist, so that sizing is slowly expanding.

Not because breasts are visible, but because it was decided they need to be supported or lifted, and so the bra needs to cup the breast without damaging breast tissue.

The band size is the actual measure plus 4 or 5 if measuring in inches. So if you measure 34, your bra size is 38, then measure around the breasts with a bra on and if the measure is 38, you are most likely 38D 38–34 is 4, but you have to try on to really fit for sure, because some vendors cut smaller or bigger. Easier to just measure for the band and go up or down for the cup based on the current bra the woman is wearing.

I ended up a perfect 36 C.
36 25 36 to be exact. Brick house!

Not to derail the thread, but @Forever_Free YOU majored in tits?

She wanted to keep abreast of changes in fashion, @MrGrimm888

@elbanditoroso @Forever_Free‘s pronouns are he, him and his.

Uh. I’ve been around awhile. I never heard of custom made bras…

Drunk History once had a story about The history of bras.

@Dutchess_III my Physical Therapist that has very large breasts, had some made and then opened a bras shop next to her office. She sells custom made ones from Canada.

I’m also a good friend with her husband.
