I love the size of my breasts, but they grew too quickly when I was young, so now they seriously sag. I'm honestly not sure what size they are exactly, other than I've never been able to find a bra in the US that fit right. From my measurements and the posted estimates of a few companies, I'm somewhere between a DDD and an I, depending on the brand. Gotta love how they can't agree on what to call the larger sizes...
Except for the sagging part and wishing they were more symmetrical, I love my breasts.
