Theoretically, Chelsea should not have a limit, as she doesn't have typical silicone/saline implants.
But, I believe Beshine does. What are her implants overfill capacity?
That question has never been discussed by Beshine. I have always suspected that she actually has been successful in placing two separate set of breast implants in each breast. This is all conjecture on my part but for argument sake let's explore the possibility that she has two pairs of 6,000 ccs expander implants. From what I understand to be correct, expander implants can be overfilled up to three times their rated size. This means that theoretically she could have up to 36,000 ccs in each breast or about 80 pounds in each breast or 160 pounds total which would mean her breasts could weigh more than her. I have seen photos of her breasts she has posted at her site and it looks like she has two fill portals per breast. Of course, I'll grant I can be totally full of shit. I still find it so incredible remarkable how large she is without seemingly injuring herself in a negative way. Beshine is a living, breathing BE fantasy in the flesh. I wish I could meet her so my eyes can feast on her. Guess it won't happen though. 
Hi Solvegas. Beshine has 1 implant per breast and 1 filling port per breast. She will show you the place to you if you are in a exclusive camshow. I believe she did show this to several people by now. Also she will tell you it is 1 implant per side.
This has nothing todo with you Solvegas. I just don't want to post 2 times.
I like her for her invention of the infinity symbol in the big boob world! And I'm member on many sites and can't remember seeing it used before in this context. Fortunately I'm not the doubting Thomas from the bible.
I've asked her before years ago in a cam show and she was coy with me and didn't tell me so I just figured she did not want to give any trade secrets and I did not ask her afterwards. I guess I was full of shit. Oh well, I was just speculating trying to fill in the blanks by theorizing about her breast expansion in a manner that seemed plausible to me.
Why I didn't think of this lady the first time! I'm thinking Haruhi Miwako should be allowed to be a card-carrying member. 
Miwako's condition, as far as I know, is caused by a natural endocrine condition, not by implants so while size wise she is in the same league as Beshine, the cause of her condition is different and it seems that in the discussion, we are mostly talking about implanted models.
