DD Cup 

Typically read as "Double D Cup"

A Brassiere cup size designation used in various systems, typically denoting an overbust that is between 5 and 6 inches larger then the underbust.

In the American system, interchangeable with the designation "E" cup but elsewhere found between D and E.

The origin of this lettering convention is uncertain but feasibly it was done to create symmetry the the AA Cup on the other end of the spectrum and remained for the euphony and whimsy of the expression.

A DD Cup is considered a large though feasible size on a fairly slim person.

A relatively big size for a woman. But there are many types of dd, so dd being one size and only one size in particular is incorrect.

A dd cup is a size of breasts in which the typical difference between the under-bust and the over-bust is 5 inches/12.7 cm.

A dd cup is perfectly fine and okay-looking to any size. There is nothing bad if a dd cup on any body type looks too big or too small. unlike mister 9inchdickman said.

If you think one dd cup woman's breasts are saggy and have stretch marks, and immediately assume that all dd cup ladies' breasts are saggy and have stretch marks, then you might need to get more bitches and touch grass than just whine about other ladies' breast size online. I for one, do have dd cups, and mine aren't saggy nor have stretch marks.

James: Damn, those boobs are huge. Are they DD-Cups?
Claire: Yes, but James, you are my husband of 2 years, how come you haven't known?
James: Claire, I'm sorry I thought you'd have small breasts because you're skinny. I've only noticed recently when you use your revealing clothes around me more.
Claire: It's fine James, now let's go to the bedroom.
James: Okay Clare.

Then they happily fucked, with Claire's dd cups that are "too big" for her skinny body.
