I love love love my big boobs (so does hubby) and they're pretty full right now--- at my top weight (302) was wearing a 40G... now I'm in a 40F... I don't recall EVER being smaller than a DDD, even at 215lbs... so I'm hoping I don't lose all my boobage.
In fact, I can't WAIT to have a trim waist and body and have these big boobs to top it all off--- Right now they kinda blend in to the rest of my big body--- I want to be a "big chested average weight girl". Think that would be awesome.
I wouldn't mind a breast LIFT after weight loss to bring them back up to where they need to be, but they scar up the underneath of the boobs really bad. So what's better? Scar tissue (I scar VERY easily) or saggy boobs? I'll have to decide when I get there... plus, they sometimes totally detach the nipple and move it somewhere new. I want to breast feed in the future, so that will be an issue too.
Like I've said in another thread--- I'm going to loose all this weight, have children in a few years, and after all that time if I'm still maintaining, then we will take a loan out and "fix up" what needs to be fixed.

That's the plan, at least.
