On the Addicted show tonight, Lacey said her boobs currently weigh 27lbs, which would be like 6100cc each, which she has had for a number of years. She had one blow out two years ago while trying to reach down into her washing machine (they get in the way of things most people wouldn't even imagine) but was able to get a same size replacement quickly. I must say, while I have no idea of size in this picture, on the show, I was thinking a bit less than 6100cc. The thing is, she announced she would soon be getting expanders with a initial fill weight of 41lbs., which would be about 9500cc.
Boobpedia seems to list her cup size at 3150, which she quoted on the show as being the previous size implants she got in 2011 with a clip talking to her son back when. The implant she holds up as her current size looks bigger than that. From what I gather, it has been some number of years, I believe 9, since she got her current implants, which has given her more than enough time to stretch and likely be able to accept a 9500cc implant.
As she explains getting expanders to her daughter, she explains the benefit; she can follow her boobie greed now that craves bigger boobs and in 10 years, when she is 65, if they seem too much, she can just drain some saline and make them smaller. I immediately had to wonder, has she thought about how all that slack skin will look? Once you stretch it, you should plan on keeping it stretched; saggy is not attractive.
